First of all, apologies if this seems vague - I'm not an admin of anything more than a home network.
I have a Ubuntu box sitting on my network which does various odd tasks for me - svn serving, some file serving, Apache/MySQL/PHP which is all raring to go.
I've started a new job and at the moment I'm using ShrewSoft VPN software to establish a VPN link to the office as I need it. I'd prefer to have something always running on my home network just for convenience. My home modem/router doesn't support holding a VPN connection open.
What I would like to do is set up my Linux box to hold open a VPN connection to my office and keep it open permanently, and then all applicable traffic for the office be routed through this box.
I'm not sure if this is possible, or how to configure the routing on the desktop PCs (Windows 7).
Would appreciate any guides, etc that could help me out.
