Connecting to SVN server behind corporate firewall from home

How can I configure TortoiseSVN to connect to a SVN server behind a corporate firewall from home? This is the question I'm having a hard time finding an answer to. Here's what I DON'T have: - Official VPN access to the corporate intranet. - Control over the SVN server. - Any control over the intranet. - Cooperation from the IT department. Here's what I DO have: - Full control over my computer at my desk at the office. - Willpower This is a shot at what I tried, and seem to be unsuccessful at (names of people and places and machines have been changed to protect the innocent): - I am using Wippien to set up a zero configuration VPN from my home computer (NG-ATHOME) to my work computer at my desk. This works, I have total network access to and from both machines. - I have OpenSSH for Windows running on NG-WORKBOX. - I have PuTTY on NG-ATHOME connecting to NG-WORKBOX to tunnel dynamically over port 1080. The SOCKS proxy is working, as I can verify that with any web browser. I can confidently say that this is not the problem in the scenario. - I am using TortoiseSVN on NG-ATHOME configured to use a proxy on 127.0.0.1:1080. When I try to hit "svn://NG-SOURCE/PonyRepository", I get error: cannot connect to host. I can ping NG-SOURCE fine. Why doesn't SVN work? Hmm, I have a suspicion that SVN does not like SOCKS. Anyone have a suggestion?
