Re: Private IP address showing up in PIX log - how to find it
If your routing table does not have the 192.168.x.x address, unless your routers have unicast RPF checking enabled or ACL's preventing this, the traffic will follow your default route. Of course, no traffic will be able to get back to the host sending this traffic, but it will be able to send traffic to just about any address until it runs into a filter or a device that performs a reverse-path check.
Turning off ip directed-broadcast (it is off by default now) only prevents the router from sending it out as a L2 broadcast, but does not necessarily stop the router from forwarding the packet.
