Probably a javascript app running locally is telling them. Or your real
address is embedded in the data portion of a packet, that the NAT
process can't change.

Subject: internal IP should be hidden ? Shouldn't it ?

My CE590 sits behind my PIX525 which sits behind my 7204VXR.

All port 80 traffic gets redirected into the CE590, 1918 addresses
gets PAT at the external interface of the cache engine. After which is
flows through the PIX before it leaves via 7204 out to the ISP.

Diagram:
INTERNET > 7204VXR > PIX525 > CE590> Switch>LAN> ME :-)

Can somebody please tell me how these guys at auditmypc can sniff my
internal address ?
