Firewall

The Firewall page allows you to create access rules for your network.

To view the Firewall page, access the Harmony SASE Administrator Portal and click Private Access > Firewall.

Use Case

• Create rules for specific user groups, resources, and protocols. For example, deny access to the management user group to a certain resource if accessed through the Internet Control Message Protocol (ICMP).

• Create a comprehensive rule for the entire network traffic. For example, block all traffic on a specific port.

Prerequisite

Define your network with IPSec or Harmony SASE Connector tunnel. See Adding a Tunnel.

Access Rules Order

The order of the rules indicate the sequence in which the system checks and applies the rules. For example, if a user tries to access a resource, then the system first checks if the traffic matches rule #1. If it does, it applies the rule. Otherwise, the system checks if the traffic matches rule #2, and so on. If none of the rules match, then the system applies the default rule.

   Note - The Source and Destination define the conditions for the Action to be applied to the traffic. You can specify three types of objects in the Source and Destination fields: Any - All traffic (any address or member). Groups or Members - All traffic routed from/to a specific member or member group. Addresses - Traffic routed from/to an FQDN, IP address, subnet, or list of IP addresses.

9. In the Service field, select one of these:

   • Any - Traffic routed on all protocols and ports.
