SNAT over IPSec XGS107-XG135

Dimitris Roubos

Hello there,

I have 2 Sophos Firewall connecting to Networks with IPSeC Site-to-Site VPN 1 Public IP for each network.

XGS107 (SFOS 19.5.3 MR-3-Build652)

XG135 (SFOS 18.5.2 MR-2-Build380)

Network A 192.168.1.0/24

IPSeC gateway 172.16.21.1

Network B 10.10.10.0/24

IPSeC gateway 172.16.21.254

The concept is that we have one Server that is accessed only from Public IP from Network A and i want to access that Server from Network B, I assumed that SNAT is the solution but I am not aware of how to setup in Sophos.

Any suggestions they would be appreciated.

    Thanks everyone for your ideas you helped me a lot, but as soon as i realised the concept i understood how to utilize the IPSeC connection.

    Network B

    I added a static route to the site's IP Address / gateway 172.16.21.254 / interface Network B to Network A

    Network A

    Then I added 2 firewall rules (1 for each directions) for allowing the site's IP Address is reachable.
