Sophos Firewall: v19.0 GA: Feedback and experiences

Parents
  • Picking up issues with NAT. I have multiple public IP's configured on a singe port all using the same Gateway which is the ISP's router. I need some outgoing traffic to come from a specific IP configure on the port.

    For this I used NAT rules and translated the source to the IP specific public IP address I want the traffic to come from. Since v19, traffic is now translated to the IP of my ISP's router, in other words, the gateway for the port.

  • Sorry for the late reply. NAT issues have been on going for a long time in SFOS. I reported this back in the V16 days, but they never did anything about it. Every once in a while on upgrades of a few different clusters, some NAT rules would just stop processing. If you had custom NAT rules, the easiest fix is to just delete them, and recreate. I also specify interfaces in NAT rules and disable the default SNAT rule. It seems to help on upgrades.
