Re: Invalid IP address

"A log entry with port 0 means that the router didn't need to inspect the
port number to allow [or deny] the traffic, such as with the following:

access-list 100 permit any any established log"

| I am seeing this on my router syslog after I applied an access list on the
| internal interface. Can anyone tell me what this could be? The 68.84.8.41
| is a comcast IP that is active on the network; however, someone inside our
| network is attempting to use it to go out to other sites? Thanks for your
| help.
