Thanks for the quick answer, so a couple of updates,
I managed to solve the vpn disconnecting every minute, it was the compression on the VPN server side, it was set to LZO I changed it to OpenVPN Defaults and it's working with no disconnections now.
This is the configuration on the Server Side Pfsense, The server gets 10.3.101.1 and the RUT955 gets 10.3.101.2
The LAN on the Pfsense Server side is 18.104.22.168/24
The LAN on the RUT955 Side is 192.168.5.0/24
The VPN config on RUT955 is
So, from the Pfsense Web UI i'm able to ping all the devices on the Teltonika LAN network, but from the Pfsense LAn(I have a windows machine there) I cannot ping neither access any of the webservers.
I presume is something with the routes or the firewall, is there any chance to disable the RUT955 firewall completely just to test that eveythings is working and then adjust it to the neccesary rules?
This is my firewall rules
I'm not a netwrok specialist, so I'm sorry if I made some big mistake :)
Thanks for all your help and time
