Pix Firewall Log Question

I noticed when doing a netstat -an there was an established connection to a 192.168.100.61 to the outside world....I have no idea who this is.... i also found something in the firewall....

Teardown TCP connection 94264 for outside:192.168.100.61/9100 to inside:192.168.10.48/60353 duration 0:  02:01 bytes 0 SYN Timeout

Could somebody please tell me what this means?? this is private address...so how could it be from the outside?

TCP 9100 is Windows standard port monitor for printer mapping
Looks like perhaps someone has a printer port mapped to this .100 subnet IP. Since it is not local to your LAN, for all intents and purposes it is outside and the PIX builds a xlate for it, but then no response ever comes back so it tears down.

I meant anything additional, if in addition to your PIX there was, let's say, a wireless router, that looks similar to the IP it would give.

nope. there is no .100 subnet anywhere around here...i know cuz i set everything up...could somebody have plugged in somewhere else in the building....and why would it show connected to my computer?

and because I have no route that points that subnet back to the inside thats why it shoots it out the default route. I knew the port had something to do with a printer from some googling, however, thanks for making everything more clear.

You Rock!
