Hi,
I have been trying for a while to set up a IPSEC VPN between a VPN-1 4.1 SP3
Check Point firewall and a Cisco 3030 concentrator.
Both ends are set up to use preshared secret, IKE encryption scheme, DES
keys/MD5, data encryption of DES / ESP and MD5.
When sending data from the Cisco to Checkpoint all is ok, but it does not
work the other way. The log file give me messages in blue of "invalid cookie"
and "payload malformed and then green of "gateway connected to both end points:
scheme IKE"
When using the same parameters between 2 checkpoint firewalls it works
fine. I have also tried 3DES without any success.
The manual suggests that these message mean "incompatible firewall". I have
been told but Checkpoint and Cisco that this should work.
Does anyone have any ideas ? Has anyone successfully done it to these
Cisco's ?
Thanks in advance.
David
