I have recently setup a PIX 501. I'm not sure if what I want to do can be accomplished, but here is what I am trying to do.
When I connect to the VPN, I have full access to everything on my network; however I use a picky SMTP server which only accepts connections from inside my network (although it is a public server).
So basically I would like to be able to send traffic to the SMTP server over the VPN connection. If I turn on the split-tunnel the traffic doesn't go over the VPN. If I turn the split-tunnel off, I still can't get to the SMTP server.
Any information as to how this can be done (assuming it is possible) would be greatly appreciated.
