[FW1] Unsuccessful VPN from Cisco PIX to FW1 4.1 SP2
I have been unsuccessful in connecting Cisco PIX to
Checkpoint FW1.
I got thorugh level 1 handshaking, but never through level 2.
The error conedition that is shown by the PIX log is
ISAKMP: reserved not zero on payload 5!
The fix is to switch to checkpoint.
Cisco support spent 8 - 10 hours supporting us. But we did
not find the magic incantation. One thing is clear.
Managing the checkpoint FW through a GUI is much much much
easier than the command line interface to the PIX.
FYI, Here is the error state.
This is Check Point VPN-1(TM) & FireWall-1(R) Version 4.1 Build 41716
[VPN + DES + STRONG]
