OpenVPN on pfSense 21.02.2 connecting to 2.4.5 wont pass any traffic across VPN
-
Hi, I am having an issue where I have a Netgate XG-7100 running 2.4.5 and a client running 21.02.2. I have managed to get a site to site OpenVPN established using TLS between the 2 sites after much messing around. The issue im having now is that I cannot get any traffic to traverse the VPN connection at all.
I have reproduced this from another client running 21.02.2 or 2.5 and have the same issue. If I try a client running 2.4 then everything works fine.
No errors in any of the logs that seem to be useful. Have tried everything. Has anyone got any ideas?
Thanks

@dannyr1992 We have managed to get the Firewalls to communicate. Turns out it was compressions settings which is madness.
Even thought the firewalls are communicating and the routing table is correct the LANS cannot communicate with each other.
Does anyone have any ideas
