Can You Also Use UDP?

[B B]

Hi ra,

From my understanding about Tor and the Tor Gateway you're supposed to use an OpenVPN server only on TCP? But today by mistake I connected to a server through UDP and ran the Tor Gateway and I was running Tor through the VPN, I checked the IP online and I was surfing online and it was working...

So can you use the Tor Gateway/Tor with UDP too?

thanks

Since Tor allows TCP only and the gateway VM drops all UDP traffic (apart from DNS), it is not possible to use UDP-based applications.

Ok, I just don't understand how I was able to then get online...

Hmm

Thanks ra

It most probably was a TCP connection. IIRC openvpn retries with TCP when UDP fails a few times.

Odd because in my openvpn.conf I had it as;

proto udp

And there is a server that has the same IP address but it is shown with a different port and proto tcp-client

hmm
