Strange Masquerading Issue

Hi.

Today I've got a call from a colleague.
From what he says - he can see in his firewall, the internal source address of some (not all) of the stations from my Lan network which connect to his servers.
Since my entire internal network doing Masquerading, I wonder how this could be.
As far as I know, only DNat transmit the source address.

Any Idea?

To any of you with production system, who want to check it too -

From SSH (Puty) Run the command:
tcpdump -i eth1 (change to your external Nic)

In putty – change to all session, and define the place to keep the log, after a few minutes, stop and look for internal IPs.
