Problem setting up racoon / Checkpoint VPN

[Paul Keusemann]

Hi,

I'm trying to set up a VPN between my FreeBSD 6.3 machine and a
Checkpoint box.   I've currently got a VPN set up between the same
machine and another Checkpoint box and it's been working fine for
four years.  The new Checkpoint box is supposed to be set up identically
(expect for the obvious address changes) as the working system but
when I try to bring up the link, I'm getting an error during the phase
1 negotiation:

2008-05-15 08:38:15: DEBUG: 40 bytes message received from 207.xxx.xxx.xxx[500] t
o 12.202.208.28[500]
2008-05-15 08:38:15: DEBUG:

00000000 0100000e
2008-05-15 08:38:15: DEBUG: malformed cookie received or the initiator's cookies
 collide.

I'm assuming this is some sort of misconfiguration but nothing that
I've tried as made any difference.  I can post my side of the configuration
but right now, I'm just looking for someone who can tell me where to
start looking.
