Hi Experts !!!
We have two firewall fwsm modules deployed on two different 6509 chassis at two different sites, connected via layer 2 link, as primary and standby modules.
NATng is enabled on the primary firewall module and all xlate and conns are getting replication to standby module.
Yesterday, suddenly NAT engine in the primary fwsm module stopped working and no inboun/outbound traffic was being passed. No changes were made.
Any ideas, what could be the issue and how it can be fixed? FWSM ver is 3.1(1)
