[FW-1] Failed to establish VPN trought the FW



Hello

We use two NG enforcement points (NG with FP-1) in a rainwall Hot Standby
configuration on Solaris.

We would like to establish a VPN connection from outsite to the internal
network (behind the
FW), Cisco-Cisco.
But the tunnel can not be established. We make a sniffertrace at the outsite
and saw ESP pakets.
Behind the Firewall we couldn't see any ESP pakets anymore.
We disabled also the "Enable decryption on accept" option.
There is no NAT between.
Before we put the new FW-Cluster (Hot-Standby) in place the Tunnel worked
fine.
The rule between this two cisco devices is accept all traffic in both
directions.
In the Log we don't see any.
The cisco-device insite is in the same subnet as the internal Interface from
the Firewall
Does anybody have an idea?
Does rainwall have some problems with this configuration?

Regards

Martin
