Hello. We have a LAN connected to a WAN and we are using 7960 SIP Phones. For privacy purposes I want to protect our actual IP so I will refer to our addresses as W.Y.Y.n (n will be an actual number). These means we have network W.X.Y and n is the different IP addresses. As a matter of fact, when I refer to IP address n I actually will mean W.X.Y.n And we actually have netmask 255.255.255.248 which limits us to 7 addresses. The WAN shows IP address W.X.Y.142 with a peer of W.X.Z.254 (Z != Y) The LAN shows IP address of W.X.Y.137 This gives us
138-141 to use as IP addresses for the SIP phone, terminals, etc. As an experiment, I tried all the addresses from 138 to 141 with a terminal. I SSHed into the machine where our SIP proxy is, and did a who. No matter what the terminal address was, the who always showed us as coming from W.X.Y.142. So say, for instance, we make the SIP address 138. The invitation will come from 138, but the machine thinks it is 142, so SIP calls won't work. Any idea how to make the actual IP address match the viewed IP address?Oh, the router in the sip phone is set to 42
