Squid allows you to configure the addresses it uses. The defaults from
squid.conf are:


This leaves the choice up to the OS. On a machine with m,ultiple
interfaces, the IP address of the interface through which the packets
leave, will be used.

I suspect you are using an IP alias with multiple IPs bound to the one
interface. In this case, I believe the OS will use the one bound to the
"real" interface. For example, on Solaris you'd have le0, le0:1, le0:2
 and I believe the OS uses the address bound to le0.
