Wired Tether via Proxy with other than Proxoid?

[ZoomStop]

Boy guys I am really frustrated and if anyone can help I will be eternally grateful. Let me lay out the issue since it is pretty easy:

At work, need internet. I have internet but it is heavily filtered (and monitored).
Have a Droid(1), rooted, froyo.
Want to tether but need my networked applications on my work computer to stay connected to the corporate LAN so I can still use email, server terminal clients, etc.

So that is the goal. Proxoid is as close as I have some. It works OK since I can just run a copy of Firefox off a thumb drive and have my proxy settings setup on there.

But Proxoid is so buggy (it seems). Connection drops often, gets VERY slow at times, etc.

I would even be willing to try a normal wired tether and pull some TCP/IP tricks if that would help (have tried to mess with the TCP/IP metrics and tried a program called ForceBindIP. The former plain didn't work and the latter had odd issues).

I thought I could use ConnectBot to replace Proxoid but I can't figure out the settings.

Any help would be awesome. Thanks!
