Is there any way possible that my un-natted private IP address can go out and get past the first ISP gateway that I hit?  My laptop has a private address 192.168.1.22 and my friend who has a web site claims that he could see my 192.168.1.22 when I attempt to access it.
As a test, I turned off natting in my router so that my 192.168.1.22 did not nat to the router public IP as it usually did.  And though his server (linux) did not respond to my private IP, as expected, he did say that his tcpdump did see my 192.168.1.22
Is that even possible???  That violates everything I thought about the private RFC 1918 address.
I could imagine that my packets sourced from 192.168.1.22 might exit my router and hit my ISPs gateway, but after that???
Does anyone have any thoughts or knowledge on this?
