The quick-fix is to run ssh with it's built in socks proxy mode, 
assuming you have an ssh login on a better-connected host.  If you 'ssh 
-D portnumber user at remote_host', you can then configure socks-aware 
applications to use localhost:portnumber as a socks proxy and the 
application's connections will appear to originate from the remote side 
of the ssh connection.  The down side is that you have to use 
socks-aware applications or get a generic proxy client library preloaded 
before the app.

A VPN with appropriate routing would do it transparently, but would need 
to be installed and configured at both ends to work.
