TCP OPVPN - Can not Route all traffic from client - UDP connection works fine



  • I have setup OPVPN many times, but this one has me stumped ATM….

    Quick setup:
    I had a working OpenVPN setup, then rebuilt my box from scratch. (both TCP and UDP servers worked fine)

    PF has two OpenVPN servers One UDP and one TCP with the same settings besides the transport.

    I restored my openVPN server settings, certs, and everything else to the new box.

    I have two OpenVPN servers One UDP and one TCP with the same settings besides the transport.

    New setup is a two PF Carp cluster, i have OpenVPN listening on local host with forwarding to that. (also tested right to an Open WAN IP with same results)

    Both servers will allow clients but only the UDP one will rout any traffic over the tunnel.
    The TCP connection will connected and i can see my test and traffic going to the firewall in the PF logs, but no replies, no internet...nothing on the client.
    NAT is setup for the OpenVPN connection, so that looks good

    The only difference i see ATM is my old box was not upgraded to Open VPN 2.3.17 yet.

    Not sure what else to check, but any ideas would be welcome....Prob just missing something.

    Thanks in advance



  • I tried other TCP ports and same results….I see the firewall passing the traffic

    UDP is working as it should...same server config..just different protocols.

    Can anyone just confirm they have 2.3.4 routing traffic using OpenVPN TCP? (this is a clean install just done...no upgrade from older versions)

    Need to make sure before the rest of my hair falls out..  :)

    thx
