[Openswan Users] Strange problem with OpenSWAN and Checkpoint Firewall-1

[Claudio Prono]

Hello all,

I have an ipsec tunnel between an OpenSWAN and a Checkpoint Firewall-1.
It work only from the openswan to the checkpoint, not the inverse. When
the Checkpoint try to communicate with the OpenSWAN, it recieve a
message like the following:

"Quick Mode Received Notification from Peer: invalid id information"

I have already checked the network declaration between the two objects,
and are right. No problem at all for the comunication from the OpenSWAN
to the Checkpoint... and that error is not in the OpenSWAN logs....

Any hint about this? If needed i can give all the configuration from the
OpenSWAN, not from the Checkpoint because i don't have access to it.

Cordially,

Claudio Prono.
