I've tried to set up a VPN server on my copy of Ubuntu 10.10 with insuccess. Community material on the topic is little and poorly documented (clients only information, scenario-specific information, WIP pages, ...)
What I need in specific is tunnelling of traffic over HTTPS to go around a proxy server that only allows HTTP and HTTPS protocols.
What I did try is following this ubuntugeek.com guide. I've gone through each step (here are my config files), set up an account through DynDns.com, set up port forwarding and set up a VPN on my copy of Windows 7:
- Endpoint: redacted
- Username: badp (I also tried delta)
- Password: redacted
I've also turned on logging on the Windows 7 side of things and attempted to connect from an unfiltered location. From the logs, it seems like the connection is dropped right after authentication takes place.
Where did I go wrong? Was there a guide on the Ubuntu official resources I could've tried instead?
Why not just use OpenVPN? It's very easy both on Windows and Linux.
Here's a straightforward guide: http://rootmanager.com/ubuntu-ipsec-l2tp-windows-domain-auth/setting-up-openswan-xl2tpd-with-native-windows-clients.html but it doesn't cover tunneling it over http/https
another solution is here: http://www.exiledmind.net/vpn-tunnel/ this maps EXACTLY to what you are trying to do.
I prefer openswan since openvpn is client number limited now
if the auth is succeeding but the tunnel isn't formed this usually means the two end-points can't agree on tunnel mode and/or crypto system. another possibility is a routing problem where the near and far networks are on the same private subnet and your traffic gets dropped because it doesn't know to transit the vpn link.
