I have been able to establish a vpn between NG FP3 HF1 and 4.1 sp3
just make sure that in global properties you choose the same configuration
as the remote. Global Properties-Remote Access-VPN Advanced is used for
backwards compatibility, I also ensured that Group 1 was enabled (768 bit)
oh and this was an upgrade so FP3 has backwards compatibility installed.
3DES,MD5,768 bit.

Subject: [FW-1] IKE Between 4.1 SP5 and NG FP2


I have set up a tunnel making sure names, config is identical and timings
are ok between 4.1 sp5 and NG FP2 firewalls and get the following error "IKE
Log: Sent Notification: invalid cookie <phase1>"
According to some resources this is a interoperability issue??

Has anyone had this in the past or can shed any light on this? Would be
really appreciated
