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.
 
HTH,
Tom

        Dear list, 

        A customer of us uses Checkpoint firewall and corresponding VPN
client for roadwarriors. 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?

        Greets, 

        Christian
