I am required to connect to one of our customers sites using the microsoft vpn client. I need to be able to do this from behind our existing PIX firewall. Our firewall currently doesnt allow this.
I have opened 1723 *outbound* on the PIX which has allowed me to see the client session begin to setup, but then the session dies.
Question 1, Do i need gre also? Inbound or outbound?
Question 2, Do i need any static mappings for the vpn device we are trying to connect to? Our internal networks are all NAT 10.1.X.X.
