OpenVPN behind HTTP PROXY Authenticate Successfully But Can't Use Internet

Post by baryonbozon » Thu Aug 05, 2021 10:23 am

Hey I want to figure out how openvpn can be used behind http proxy to direct all my traffic.

I was able to do it using other tech different than openvpn for TCP connections but UDP not . Before I did them:

1-I used redsocks smoothly to direct all tcp conenctions. But could't do it for UDP. 2- I used ssh dynamic tunneling and created a socks proxy. I used it with redsocks. But still couldnt do it for UDP.

So I considered using openvpn to get all my traffic and use internet for UDP and TCP behind dorm proxy.

I used http-proxy settings to use my dorm proxy once. It could be Authenticated and sequenced succesfully but couldn't use internet.

I used socks-proxy settings to use my ssh dynamic tunnel through dorm proxy. It could be Authenticated and sequenced succesfully but couldn't use internet, either.

I am forcing my openvpn to use TCP only because I know the restrictions about using udp with proxies.

I can use my openvpn server with cellphone internet smoothly but can't connect internet with dorm network.

It is my last week in my school and I never tried to do anything forbidden. I just want to know HOW in my last week. If you help, I appreciate you !

it is my client.ovpn's critic part:

Code: Select all

remote amazon-ec2-ip 443 tcp
route amazon-ec2-ip 255.255.255.255 net_gateway 

dev tun
dev-type tun
http-proxy school-proxy-ip 3128 ntlm ntlm // it use ntlm auth. so I prepare ntlm file to auth it, it works dont worry.
http-proxy-timeout 5m
http-proxy-retry

allow-pull-fqdn
redirect-gateway def1
it is what openvpn says(only critic parts):

Code: Select all
