Hi Christian, You need to make the clients SecureNAT if you want to allow them to use outbound PPTP. Beware of the "bump in the stack phenom" (ask Stefaan Pouseele about that one!) and the Firewall client with NAT-T configs.

Now our company needs access to their internal network. I have two ideas how to accomplish this: (1) Install the chekpoint VPN client on internal clients and let them access the customers Checkpoint with ISA Firewall client. (2) Create a VPN connection directly from the ISA server. I know it is very important to know what kind of VPN protocol they are using (L2TP / PPTP / IPSEC / proprietary Checkpoint) but unfortuantely I don't know it yet. I just want to hear some comments if above points might be possible to get up and running. Maybe someone in this list has any experience with Checkpoint?
