I am attempting to configure Checkpoint Express Gateway to Gateway IPSEC VPN with the following parameters:
- Both sites are using Checkpoint (Local: Checkpoint Express NG, remote: Checkpoint Firewall1/VPN1 4.1)
- Remote Gateway must be configured as an Interoperable device
- IKE and pre-shared key
Is there any documentation available anywhere that would give me some detailed instructions on how this is done? I have attempted using documentation from Checkpoints website, but that doesn't seem to help. I also have the latest Checkpoint NG book (Phoneboy's) but the specific example doesn't work for me. This must be relatively simple, but I am not having much luck.
