RE: Two VPN clients on one computer

[Shawn Wall <sjwall () shaw ca>]

If you need to connect to different remote networks via VPN on a regular
basis, you may want to consider a persistent VPN by using routers or
firewalls that support such features. You'll need one device on your gateway
and one at each target location. Security can be configured to allow only
desired hosts/ports through the VPN. This will eliminate client VPN software
issues on the desktop and provide transparency to the users.

The answer is yes you can. 
Be aware with such a setup on a vpn you may be exposing the first
network to all the others. 
The machine with the two clients may act as a bridge and mesh the two
vpns together, generally not a good career move unless this has been
asked for.

If you do you end up with:

network1 server (1) ----- VPN -------- network2 client(1) --- Network2
                                            |
                                            | Transparent 
                                            | Connection
                                            | VPN
                                            |
                                         network 3

This may be what you want.It may not be what you want.
In any case if you search Google for "VPN Mesh internetwork security"
you will get some ideas about what it is your are dealing with.
Be aware that there is an excellent open source package called OpenVPN.
