My thoughts are like this:
I have this external vpn service that I am connecting to. But Is it possible for me to set up a local proxy server that uses that vpn connection, so applications that connects throu that proxy uses the vpn? This is applies to a Linux system.
Hints and links are welcome!
EDIT: Use case:
Perhaps there is another way to do this.
Router #1 - Connects by the default net provided by ISP
Router #2 - Connects by PPTP VPN to another 'ISP'
Clients in network are by the default connected to the normal router #1 and all traffic gets handled by that.
Client have a different browser (opera) that connects via a proxy on router #2 and ends up at the end of the VPN tunnel.
Does this clearify?

Although the situation you have described is not possible (running application can not override system routing table) you may have a couble of options:
man ssh_config
