    Hi merowinger,
    The Checkpoint uses IPSEC so you need to open UDP port 500 and esp. I.e:-
    access-list outbound permit udp any any eq 500
    access-list outbound permit esp any any

    I have also seen talk of TCP/265 and port 256 (dont know if UDP or TCP). If you allow all these you should be fine.
