Openvpn troubles - help me understand iptables

  • I am facing an odd situation with an OMV4 server. It has OpenVPN running (as a plugin, tried also pivpn) and I am able to remotely connect without issues. However, since some updates and restarts from last night now I can connect to the OpenVPN server but cannot reach any service hosted on the machine's physical ip - no http, no ssh, ping oddly works. Internet access and access to other clients works fine through the tunnel.

    Also, if I connect to my router's OpenVPN, I can't even ping the server in question which is connected to the same router.

    I presume this all has to do with its firewall and ip table rules, but I don't know where to start. Any help is appreciated!
