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?

          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.
