SOPHOS XG V18 FIREWALL RULES & NAT POLICIES

11/29/20 - firewall,sophos,kb

In XG v18, NAT policies were split from Security(Firewall in XG) rules. You can, however, create a “linked” NAT rule, which will only trigger when traffic passes that specific Security rule. But this won’t be covering that method.

Instead, this will be covering how to setup Firewall/Security and NAT rules on a system which splits those rules. In many firewalls you will come across, Security and NAT rules are kept and created separately.

This also largely covers the theory of firewall rules and NAT policies. While it is sort of brand specific to Sophos XG’s, the concept works across the majority of major firewalls.
