Default VLAN tagging and FW1 NGX 6.0

Hello,

I have to solve a strange problem with solaris 10/01 and FW1 NGX60.
I've a tagged vlan switch-port (vlans 40 and 50) connected to a ce-quadcard-port and configured two vlans as ce40005 and ce50005, as supposed by SUN-manpages.
If CP FW1 is down, the vlans can connect as expected, if FW1 is up, the following mysterious behaviour occur :

- a Ping from physical interface ce3 to a physical interface ce0 = success
- a Ping from physical interface ce3 to a vlan-interface ce50005 = error (i can see a echo-request with snoop)
- a Ping from Client connected to vlan 50 to an address behind ce3 = error ( i can see a echo-request from vlan-client and echo-response from destination on interface ce3, but no echo-response on vlan-interface ce50005)
- a Ping from Client connected to vlan 40 to an address on vlan 50 = error (I can snoop only a echo-request in ce40004, no echo-response)

The ruleset allows ping to all the source and dests, an the log shows the incoming request as accepted.

Is there anything I forgot to successful configure vlans on CP-Fw1?

Thanks in advance
