Tunneling through private OpenVPN on port 53

To bypass restrictions of open HotSpots, I've created my own OpenVPN server in the cloud listening on port 53. I was able to successfully tunnel through it while I was on a tethered connection through my mobile phone.



In most WiFis I am encountering the following error though:



TLS Error: client->client or server->server connection attempted from [AF_INET]xxx.xxx.xxx.xxx:53


I am assuming the routers of those WiFis intercept DNS traffic and drop invalid packets or is there a configuration I could use to work around that?

  • Do you use UDP or TCP for OpenVPN? The default of UDP often causes such problems.

DNS traffic on various ISPs and or Hotspots is often indeed often intercepted, so you can't rely on a random protocol (OpenVPN or others) to work just by pretending it is DNS.



Either pick a different port, or use some sort of tunnel that's built for IP over DNS, e.g. iodine.
