Using VPN with a proxy
- Thread starter qwerty
- Start date
I am intrigued...tell me more...
Setup an SSH server on port 443 (HTTPS) on your destination PC.
Use PuTTy and connect to it and instruct it to tunnel whatever ports you want over SSH and to your local box.
Whether it will work varies from proxy to proxy, but I have got out of the most Nazi of HTTP proxies and tunnelled 8080 to a proxy server running at home for web browsing and 5900 for VNC.
There is a windows binary called OpenSSH which I used, its no longer maintained but it works.
The premise of using port 443 is that its an accepted port on a HTTP proxy that carrys encrypted packets anyway.
Much newer version of some proxys, WebMarshal for example can open up HTTPS traffic and inspect it... so like I said, depends on the proxy and config

Depends on the type of VPN, SSL VPNs can usually be bent around obstacles easily as it operates at a higher protocol level than it's counterparts. IPSec PPTP or L2TP are not as flexible as they tend to rely on certain ports being open and these ports are not as easily moved as SSL.
