If anyone hits those ports, add them to a "potential scanner" list. If that same src IP hits those ports again, add to block list. Change the trigger ports as necessary if you're actually running services from them. You can also set it up so it OpenVPN can run over User Datagram Protocol (UDP) or Transmission Control Protocol (TCP) transports, multiplexing created SSL tunnels on a single TCP/UDP port (RFC 3948 for UDP).. From 2.3.x series on, OpenVPN fully supports IPv6 as protocol of the virtual network inside a tunnel and the OpenVPN applications can also establish connections via IPv6. Port 53 udp is reserved for DNS traffic. Even though you may have gotten OpenVPN to work on this port you are seriously blocking the server's ability to resolve DNS queries. I would strongly advise you to use a different port, one that is not in use by other services on that machine before even attempting to fix the issues you're seeing.

Has anyone successfully done a config like this? As soon as I try to change the server port from 1194 it doesn't connect at all - however I may have totally misunderstood how to achieve this with openVPN.
