No problem - my bad - I should have provided more details upfront. With the
SonicWall's VPN I can configure the firewall's VPN polcy to either 'split
tunnel' the session or force the client to access via only a secured gateway.
I agree if the PC is already infected then it does not matter - somehow
the firewall that the VPN is going through needs to somehow filter/scan the
VPN tunneling session for virus/worms/spyware etc..I'll check with my
Sonicwall firewall vendor if they have this security feature....
Thanks again for your feedback. Appreciated it.
