Hi there! I have a SOPHOS UTM firewall/router which my network sits behind (IP address of SOPHOS UTM is: with two interfaces (WAN and LAN)) and then I have a secondary firewall (pfSense) (IP address of pfSense is and has only one interface LAN) which I need all SSH (port 22) traffic funneled through (pfSense will be setup with Suricata package to inspect traffic) and then from there - traffic should be funneled back through the SOPHOS UTM to the outside. Currently Sophos firewall rule allows traffic out from internal LAN to WAN on port 22 and that all works perfectly as it should. However for specific testing reasons, I need the SSH traffic on port 22 to be funneled through Suricata (running on pfSense box) and then back to the SOPHOS to go outside. So will look like this:- Internal client computer (Using putty) (IP: Wants to connect to external server (running SSH on port 22) with IP address of: 203.223.xxx.xxx SOPHOS UTM -> Using either static/policy routes of NAT will redirect all SSH (22) traffic that attempts to go to 203.223.xxx.xxx to PFSENSE internal firewall ( PFSENSE -> Suricata performs logging/inspection of this traffic. PFSENSE -> Routes SSH traffic back through SOPHOS UTM SOPHOS UTM -> Finally routes this traffic out to end destination (203.22.xxx.xxx) on PORT 22. I've used SNAT rules on SOPHOS UTM to direct SSH traffic to the pfSense firewall without any problems... what I cannot figure out is how to re-route this traffic back to SOPHOS UTM and to the outside world. I need a networking/firewall expert to help me figure this out. Direct access cannot be given - I may consider allowing Teamviewer into network in worst case. For someone whom knows their stuff, this could be a fifteen minute task.
