Many public WiFi APs i.e. libraries, block all but a few ports. Alternatives are 80 and 443 which are TCP and as such slower. How does one run OpenVPN on Port 53? I get this one i try: "openvpn[]: TCP/UDP: Socket bind failed on local address [AF_INET]wan_ip_here:53: Address already in use" I understand that the DNS Forwarder is already on Port

Pour changer le port utiliser, proto udp port 123 Notre service écoute sur la majorité des ports que ce soit en TCP ou en UDP grace à la magie d'un PAT. Cette fonctionnalité n'étant disponible qu'en IPv4 dans le noyau Linux, assurez vous de passer par IPv4: "udp6" et "tcp6-client" peuvent passer par IPv6. OpenVPN peut être utilisé en mode VPN route ou passerelle et il peut être configuré pour utiliser UDP ou TCP. Le numéro de port peut être également configuré, mais le port 1194 est l'officiel. Et il utilise seulement ce port pour toutes les communications.

But I've been experimenting with trying to use openVPN client to forward all traffic over UDP 53 (or another specified port) to try and avoid badly set up captive portals. 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.

But: When the OpenVPN-Server machine is acting as UDP Server it answers request on the wrong port. netcat -u -l 4444 but the messages from the server back to the client leave the client again on port 1024.
01/10/2018 Set traps on TCP ports 20,21,23,25,53,9000,3306,3389,5900,8080, UDP ports 53,161,162,69,1900. 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. The OpenVPN protocol itself functions best over just the UDP protocol. And by default the connection profiles that you can download from the Access Server are preprogrammed to always first try UDP, and if that fails, then try TCP. Unfortunately, on some more restrictive networks, all traffic except very commonly used ports are simply blocked. OpenVPN est un protocole extrèmement versatile et flexible. Il a été conçu pour de multiples usages avec le maximum d'ouverture. La configuration habituelle d'OpenVPN utilise le protocole UDP et le port "standard" 1194 assigné par l'IANA.
