Cisco Cisco Catalyst 6500 Series Firewall Services Module

When an outside NAT rule is configured on the FWSM and NAT control is enabled, inbound traffic 
not matching that rule is being silently dropped.

Workaround: There are two options for getting around this. If possible, disable NAT control by 
entering the no nat-control command. If there are a limited number of networks on the outside 
coming in, a static outside NAT rule can be configured for those specific networks. For example:

static (outside,inside) 192.168.10.0 192.168.10.0 netmask 255.255.255.0

FWSM gives an error and discards the configuration when overlapping static commands are 
configured. For example:

static (inside,outside) tcp 192.168.1.100 www 192.168.2.100 www netmask 

255.255.255.255
