Folks,

I subscribed to the gphoto mailing list in order to get hints to support my newly-bought iRiver T30 (turns out that a support is already included in SuSE 10.0 - I say 'a support' because it's rudimentary, but it works).

Anyhow, when I subscribed I got the following usual reply, but with a strange IP:

"We have received a request from 10.3.1.93 for subscription of your email address ..."

My localnet is in the 192.n.n.n range. I go through a Linksys router who gets assigned an IP in the 64.n.n.n. or 66.n.n.n. by the ISP (as visible on the Linksys WRT router web interface).

So why this 10.3.1.93 ? Has anyone noticed this kind of rather strange local IP before in such subscription replies ? Why is the mailing list robot thinking that I'm 10.3.1.93 ? Could it be that at that time the traffic was going by some 'third party' that intercepts and forwards both ways, configured in an unwise manner ? Or can an ISP route internally and routinely the traffic through several machines (eg. spam processing, etc...) and makes it such that his internal localnet IP appears ?

I'm puzzled. Anyone seen that before and pondered about it ?

Cheers.

Even more puzzling is that 10/8 is a private network address range.

My guess is that the mailing list server is behind some sort of (ill-configured) NAT device or reverse proxy.
