Traffic that is coming from the MSFC is not seen by FWSM. (Routed mode.)
Monitored the MSFC vlan 4094 interface (traffic was seen) and monitored the FWSM interface outside on VLAN 4094 (traffic was not seen).
This is nat 0 traffic and equal security levels are set on FWSM. Other natted traffic is working fine too.
Help would be appreciated.
