Last month I had no other alternative but to reach a server through a Check Point's VPN. Fortunately the editor provides a Linux client to access its proprietary stack.
Just for reference, the build working for me is numbered
800005013, and here is a copy of what to expect when the connection succeed:
$ snx -s vpn.example.net -u my_user Check Point's Linux SNX build 800005013 Please enter your password: SNX - connected. Session parameters: =================== Office Mode IP : 10.32.10.23 DNS Server : 10.168.10.1 Secondary DNS Server: 10.168.10.2 Timeout : 3 hours
