Configuring Internet Connectivity

The Device > Internet page shows how the appliance connects to the internet.

On this page you can:

  • Configure a single internet connection or multiple connections in High Availability or Load Balancing configurations. When multiple internet connections are defined, the page shows them in a table.

  • Add a new connection and edit, delete, or disable existing connections.

  • Monitor the servers and internet connections (see Monitoring).

We recommend you contact your local Internet Service Provider (ISP) to understand how to configure your specific internet connection.

Note - ADSL/VDSL settings are relevant only for devices that have a DSL port. . In 1570 / 1590 appliances, you can also configure a DSL connection over the DMZ port (see To configure an internet connection over the DMZ port:).

To configure an internet connection:

  1. Click Configure Internet (if not configured at all), Add (for another Internet connection), or Edit.

    The New or Edit Internet Connection window opens.

  2. Configure the fields in the tabs as described below.

The Configuration tab

Note - When you change the connection type, the appliance may disconnect from the internet.

  • Connection name - Enter a name for the connection or leave the default "Internet<N>" label (where <N> indicates an incrementing number).

  • Interface name

  • WAN (IPv4 /IPv6) or DMZ is for most types of Internet connections.

    You can configure multiple static IPs over the same WAN interface.

    The DMZ port has 2 inputs: LAN (RJ45) and SFP. In non-VDSL 1570 / 1590 appliances, you can use an external DSL modem connected to the DMZ SFP port. - Only Check Point Branded SFP DSL is supported. Third party SFP DSL is not supported.

    Note - DMZ is not supported in 1530 / 1550 appliances.

  • LAN. You can also use unassigned LAN ports with no VLANs for internet connections. When you delete the internet connection, the port reverts to an unassigned LAN.

  • Link aggregation (Bond) - Create a link between two or more interfaces. This improves performance and redundancy by increasing the network throughput and bandwidth. A WAN or LAN bond can act like a regular internet connection in the cluster flow. A WAN bond in a cluster can be a monitoring interface.

  • USB/Serial is for cellular modems

  • ADSL/VDSL. If you select the ADSL/VDSL interface, you must select one of these for the connection type: PPPoE, IPoE - static IP, or IPoE - dynamic IP.

You can create a maximum of 32 internet connections. This includes alias IP connections.

Note - If you remove or disable a LAN, any assigned alias IPs are also removed.

Unassigned LAN ports use case - If your company is in a region where internet connections supplied by ISPs are unreliable and experience multiple disconnections, you can connect your appliances to multiple internet connections from different ISPs.

To configure an internet connection over the DMZ port:

  1. On the Configuring Internet Connectivity page, click New to create a new internet connection.

    The New Internet Connection window opens in the Configuration tab.

  2. For Interface, select DMZ.

    • For a DSL over DMZ Connection, select SFP-DSL.

    • For a non-DSL connection, select RJ45/SFP-Fiber.

  3. Click Apply.

Note - If the appliance has an internal modem, an external modem is not supported.

IPv4 connection types

Select the connection type:

  • DHCP - Dynamic Host Configuration Protocol (DHCP) automatically issues IP addresses within a specified range to devices on a network. The device retains the assigned address for a specified administrator-defined period. This does not apply to the ADSL/VDSL interface.

  • Static IP - A fixed (non-dynamic) IP address. If you want an alias IP, configure another static IP type connection on the same internet port. Example: WAN and WAN:1 (WAN:1 is the alias IP).

  • PPPoE - A network protocol to encapsulate Point-to-Point Protocol (PPP) frames inside Ethernet frames. It is used mainly in DSL systems. PPPoE can run directly over the ADSL/VDSL interface as well as the DMZ interface with the SFP port. It can also run over WAN or DMZ interfaces that are typically connected to an external DSL modem. You must enter the IP address, the subnet mask, default gateway and DNS Server Settings.

  • IPoE - dynamic IP (DSL only) - The Internet IP of the appliance is imported through DHCP.

  • IPoE - static IP (DSL) - The Internet IP of the appliance is determined statically. You must enter the IP address, the subnet mask, default gateway and DNS Server Settings.

  • PPTP - The Point-to-Point Tunneling Protocol (PPTP) uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets.

  • L2TP - Layer 2 Tunneling Protocol (L2TP) is a tunneling protocol. It does not provide any encryption or confidentiality but relies on an encryption protocol that it passes within the tunnel to provide privacy.

  • Bridge - Connects multiple network segments at the data link layer (Layer 2).

  • Bridge DHCP - The bridge is configured as a DHCP client and the DHCP settings (including IP and subnet) are removed.

  • Cellular - This is for appliances with an internal LTEClosed Long Term Evolution - a standard for wireless broadband communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies. It increases the capacity and speed using a different radio interface together with core network improvements. modem. Both SIM cards are used for the internet connection with a failover between them. The cellular connection can be over IPv4 or IPv6 and is configured the same way in both.

  • Cellular Modem - Connect to the Internet with a cellular modem to the ISP through a 3G or 4G network. For this option, select the USB/Serial option in the Interface name.

    Note - Only one cellular modem is supported. Appliances with an internal LTE modem do not support an external USB modem.

Enter the relevant data for the connection type fields.

Note - You cannot use these characters in a password or shared secret: { } [ ] ` ~ | ‘ " \ Maximum number of characters: 255

IPv6 connection types

Important - The device can have only a single IPv6 Internet connection.

  • Static IPv6 - A fixed (non-dynamic) IP address.

  • Obtain automatically (DHCPv6/SLAAC) - In both Dynamic Host Configuration Protocol (DHCP) and Stateless Address Auto Configuration (SLAAC) the user does not set the IP as this is handled by the router/DHCP server. DHCPv6 issues a full IP address. SLAAC issues an IP address prefix, and the gateway completes the rest of the address according to discovery protocols.

  • PPPoE (IPv6 only) - A network protocol to encapsulate Point-to-Point Protocol (PPP) frames inside Ethernet frames. It is used mainly with DSL services where individual users connect to the DSL modem over Ethernet and Metro Ethernet networks.

  • PPPoE (IPv4/IPv6) - Same as PPPoE ( IPv6 only), but the user must first configure a type IPv4 PPPoE internet connection on the same interface. Use this option when the ISP provides both IPv4 and IPv6 addresses through the same PPPoE connection. This prevents the need to define the same dialer connection details more than once.

  • IPv6 Bridge - A Layer 2 bridge between internal and external networks, containing both IPv4 and IPv6 addresses (or just IPv6) to make the gateway reachable through the bridge in a dual stack/pure IPv6 network.

To configure a new internet connection (IPv4):

  1. In the Internet Connectivity page, click Add an IPv4 Internet connection.

    The New Internet Connection window opens.

  8. Configure the relevant fields in the Advanced tab (based on the connection type).

  9. Click Apply.

Prefix Delegation (IPv6 only)

When an internet connection has prefix delegation enabled, the gateway can request a prefix (in addition to an IP address) from the server and configure an internal network DHCPv6 server that uses this prefix. Connected devices are then routable without the need to use NAT.

These connection types support prefix delegation:

  • PPPoE-IPv6

  • LAN-IPv6

  • VLAN

  • Switch

  • Bridge

To enable prefix delegation in an IPv6 connection:

  1. On the Internet Connectivity page, click New to create a new IPv6 connection.

    The New IPv6 Internet Connection window opens.

  2. In the Advanced tab, select the checkbox for Enable prefix delegation for this internet connection.

  3. Click Apply.

    Note - Configure the settings for this internet connection in the Configuration tab.

A network or bridge with prefix delegation enabled must have the IPv6 Auto Assignment set to SLAAC, DHCPv6, or Disabled.

For each delegated network, the behavior depends on the IPv6 Auto Assignment settings:

IPv6 Auto Assignment setting

Delegation Action

Disabled

Address range is set according to the prefix and subnet. The DHCPv6 server is automatically enabled when it recieves a prefix.

SLAAC

Addresses are provided via Stateless Address Auto Configuration, according to SLAAC rules. The prefix and subnet are provided.

DHCPv6

Address range is set according to the prefix and subnet.

Neighbor Discover Protocol (ND Proxy) - IPv6 only

On some IPv6 networks, where prefix delegation is not supported, you can use the Neighbor Discover Protocol (ND proxy) to assign globally-routable IPv6 addresses to internal (LAN) interfaces and hosts.

Workflow:

  1. The Security GatewayClosed A dedicated Check Point server that runs Check Point software to inspect traffic and enforce Security Policies for connected network resources. receives a globally-routable /64 IPv6 prefix from the ISP through a dynamic IPv6 internet-connection, using RA (Router Advertisement).

  2. Instead of assigning an IPv6 address to the internet-connection interface (using SLAAC), the address is assigned to one of the internal interfaces(LAN/DMZ/bridge/etc.).

  3. SLAAC is enabled automatically on the internal network/bridge. Hosts behind this internal network/bridge receive a globally-routable IPv6 address automatically.

  4. The internet-connection interface is not assigned with any global IPv6 address, but still has a link-local IPv6 address.

  5. A default-gateway route is created to the ISP's gateway link-local address (as with all IPv6 internet-connection).

  6. ND proxy is used to answer Neighbor Discovery requests from the ISP side to the internal network for hosts that were assigned addresses with IPv6 prefix received from the ISP.

To enable ND Proxy:

  1. In the Configuring Internet Connectivity page, click New/Edit the IPv6 connection.

    The Edit Internet Connection window opens in the Configuration tab.

  2. For Connection type, select Obtain automatically (DHCPv6/SLAAC).

  3. In the Advanced tab, expand the Neighbor Discovery proxy section.

  4. Select the Enable Neighbor Discovery proxy checkbox.

  5. Select your local network from the drop down menu.

  6. Make sure NAT Settings are disabled:

  7. Expand the NAT Settings section and select the Do not hide internal networks behind this Internet connection checkbox.

  8. Make sure Prefix Delegation is disabled:

  9. Expand the Prefix Delegation section and make sure that Enable prefix delegation for this Internet connection is not checked.

  10. Click Apply.

DS-Lite (Dual Stack Lite, IPoE)

DS-Lite is a connection type used by ISPs to provide internet access to IPv4 networks and services. It can be WAN, DMZ, or an unassigned LAN port. You can use DS-Lite to carry IPv4 traffic over an IPv6 tunnel between the gateway and a server.

IPv6 connection types:

  • DHCPv6

  • PPPoE

  • Static IP - WAN, DMZ or unassigned LAN port.

The DS-Lite master WAN connection type must be one of these:

  • Dynamic IPv6

  • Static IPv6

  • PPPoEv6

  • Bridge IPv6

To enable DS-Lite:

  1. In the Configuring Internet Connectivity page, click New/Edit the IPv4 connection.

    The Edit Internet Connection window opens.

  2. For Connection type, select DS-Lite.

    Note - Make sure the interface type is the same for both IPv4 and IPv6. For example, if the IPv4 the interface is configured as WAN, the IPv6 interface must also be configured as WAN.

  3. The AFTR address field is displayed.

    Note - This field is not mandatory when the IPv6 connection type is DHCPv6.

  4. In the Linked connection field, select the IPv6 connection name.

  5. In the Advanced tab:

    • Set the default MTU of the DS-Lite interface to 1460 (IPv4 default = 1500)

    • Set the size of the IPv6 header to 40.

  6. Click Apply.

IPIP

IPIP, a variation of DS-Lite, is used to tunnel IPv4 traffic over IPv6-only networks. As in DS-Lite, the IPv4 traffic is tunneled over an existing IPv6 connection. The DS-Lite/IPIP tunnel is created between the client (gateway) and a peer (AFTR which resides on the ISP and is configured statically or acquired via DHCPv6).

IPIP uses the same IPv4-over-IPv6 tunnel as DS-Lite, but you can configure a static IPv4 address, which is globally routable.

The gateway first establishes an IPv6 connection to the ISP. The IPv6 address consists of:

  • Prefix - Obtained using prefix delegation or RA messages (SLAAC).

  • Suffix - Configured by the user

Comparison of DS-Lite and IPIP:

  • Both DS-Lite and IPIP use an IPv6 internet connection to carry the IPv4 traffic.

  • DS-Lite – The gateway address is non-globally-routable and automatically selected from the subnet 192.0.0.0/29.

    IPIP - The gateway address is globally-routable and you configure it manually.

  • In both DS-Lite and IPIP, you can get the prefix of the IPv6 address dynamically using SLAAC.

  • DS-Lite – The IPv6 address is automatically generated based on the acquired prefix and an auto-generated suffix, based on the interface Ethernet MAC address.

    IPIP - The IPv6 address must end with a manually configured suffix.

  • When the prefix of the IPv6 carrying the IPIP connection is changed, you must notify the IPIP tunnel provider over HTTP.

The WAN connection type of the IPIP master must be Dynamic IPv6.

To enable IPIP:

  1. Enable the IPIP feature in Advanced Settings.

  2. Configure an IPv6 Internet connection.

  3. In the Configuring Internet Connectivity page, click New/Edit the IPv4 connection.

    The Edit Internet Connection window opens.

  4. For Connection type, select IPv4 over IPv6 (IPIP).

    Note - Make sure the interface type is the same for both IPv4 and IPv6. For example, if the IPv4 the interface is configured as WAN, the IPv6 interface must also be configured as WAN.

  5. The AFTR address field appears. This field shows the hostname or IPv6 address for DS-Lite/IPIP tunnel.

    Note - This field is optional when the IPv6 connection type is DHCPv6.

  6. In the Linked connection field, select the IPv6 connection name.

    This is the IPv6 Internet connection index on which the DS-Lite/IPIP tunnel is defined.

    Note - The IPIP tunnel and its linked IPv6 connection must be on the same appliance port.

  7. In VNE Settings, select Transix for the Service name.

  8. In the Advanced tab:

    1. In the IPv4 over IPv6 (IPIP) Settings section, select Enable static IPv6 suffix.

      Note - This is configured in the IPv6 connection configuration window. Otherwise, IPIP is configured on the IPv4 connection.

    2. Configure the default MTU of the IPIP interface to 1460 (IPv4 default = 1500). The size of the IPv6 header is 40.

  9. Click Apply.

Switching the Active Image

For Security Gateways with cellular Internet connections, you can switch the active image between carrier-approved firmware configurations.

The image contains files used to configure the module for use with specific carriers. Multiple images can be stored on the device. During a firmware upgrade, you can add images packages to the module or replace an image with a newer version.

Note - You can only switch to an image already uploaded to the module.

The image package contains these files:

  • Firmware file – Contains the module's firmware.

  • Carrier Configuration file (the Product Release Information or PRI) – Contains custom settings for a specific carrier and is linked internally to a specific firmware file.

The module runs an active image which contains a single uncompressed copy of a firmware file and a single configuration file.

To see a list of available carriers and their image packages, go here.

  • EM7455 – Global region

  • EM7430 – APAC region

Use cases:

Some carriers require the module to run a specific carrier configuration file, and may also request this for the certification process. In addition, the carrier configuration file ensures the use of carrier-specific parameters when you register with that carrier.

To select an active image for a SIM:

  1. In Device > Internet, double click an existing cellular connection, or select the connection and click Edit. You can also click New to create a new cellular connection.

    The Edit Internet Connection window opens.

    • Switches - The MTU is assigned to the switch itself, not the LANs that are assigned to it.

    • Bonds

    • VLANs - The VLAN MTU must be lower or equal to its parent MTU.

    You can not apply an MTU on:

    • Interfaces assigned to switches or bonds.

    • Bridges - Configure the MTU separately for each of their children.

    • Aliases

    • Virtual access points

    To avoid fragmentation (which slows transmission), set the MTU according to the smallest MTU of all the network devices between your gateway and the packet destination

    For static and DHCP mode, set MTU to 1500 or lower.

    For PPPoE connections, set MTU to 1492 or lower.

    Note - When the gateway is behind a modem that works as a NAT device, the MTU value of the gateway must be the same value as in the modem. If the modem has a PPPoE connection, set the MTU in the gateway to 1492 or lower.

  • MAC address clone - If you select Override default MAC address, you can override the default MAC address used by the Internet connection. This is useful when the appliance replaces another device and wants to mimic its MAC address.

ISP Redundancy - supported in IPv4 connections only

Multiple Internet connections can be configured in High Availability or Load Sharing modes. When you configure more than one Internet connection, the Device > Internet page lets you toggle between these options. The Advanced setting of each Internet connection lets you configure each connection's priority or weights based on the set mode.

  • Clear the Route traffic through this connection by default checkbox when you do not want this Internet connection used as a default route for this gateway. The connection is used by the device only if specific, usually service-based, routing rules are defined for it. This is commonly used when you have a connection that is used for dedicated traffic. When you clear this option, this connection does not participate in High Availability or Load Balancing.

  • High Availability - Priority - Select the priority for the connection. Lower priority connections are only used if higher priority connections are unavailable.

  • Load Balancing - Weight - The traffic to the Internet is divided between all available connections based on their weights.
