IPv4 Connection Types

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.

• 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 LTE 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.
