VMWare SSH tunnelling (+proxy?) problem


Hi,

First post so please be gentle

My work network has various restrictions on how to get out of it, only ports 80 and 443 are allowed out and there is a proxy in the way that requires authentication.

I connect to my Linux box at home, from work, in the following way:

Using putty:

SSH to my public IP/hostname on port 443. Use putty to get through the authenticating proxy server. I believe it's possible to use something called connect.c on Linux, but I haven't worked out how to do this yet. Hence my use of Windows + putty.

At the other end I have a normal ADSL router which forwards port 443 on my Linux box to port 22 on the router. There is no firewall running on the Linux box

I then use putty to tunnel ports through the established connection to use various things on the network at home, e.g. RDP, FreeNX, VNC.

This worked fine until yesterday when I installed VMWare Workstation 5. It even worked fine after I installed it, I created a Windows VM on it (for now, there's still some Windows software I use). I was installing Windows on the VM over the link from work and all was fine, when suddenly, I lost all connectivity. This happened to coincide with the part of the XP install where it determines network settings.

At first I thought it was a hardware failure, but I got home to find everything working fine, hardware- and network-wise (I run amule and a bittorrent client on the box, amongst other things) and from inside my home network, everything worked fine, I was able to SSH in and everything just fine.

My question really is to do with VMWare running on a Linux host with a Windows guest, the ins and outs of VMWare's virtual networking, and whether anyone has had any experience of this (admittedly unusual) situation.

I haven't had a chance to look at any logs or anything, but I'm going to do some testing tonight to see what I can turn up...

Thanks

Jerry
