Duplicate Packets with R65 and VRRP on HP Procurves.

[craxnet]

Hi Checkpointers.

I have a strange behavior on our Checkpoint XL R65, - duplicate packets.
We are having a virtual gateway built by two HP Procurves 5406, firmware 12.51. They have a static route to the XL Cluster 10.1.4.1.
When i send a ping from the firewall or from internal LAN over the central gateway over the firewall to a host outside our LAN, all packets will be duplicated.
When i disable VRRP on the Procurves everything is ok.
but packets will be not duplicated when they whihin the local LAN.

How different is Checkpoint Cluster Protocoll from VRRP?
Does it make trouble to run to run different virtual routers (VRRP or CCP) in one subnet?

has anybody seen it before?
