Hi,
My ser proxy is sitting between two networks with an interface on each, the back end is on an rfc1918 range and the front end is on an internet routeable address range. I'm doing some rewriting of address to relay anything for **XXXXXX@thisdomain.com to XXXX@thatdomain.com as fwd does.
The problem I have is that if a requests comes in on the private interface, the address gets stripped and rewritten properly and the request goes out, but the source address of the INVITE (as in the ip source address) is of the private interface that the packet came in on. It's therefore being dropped by my ISP, and wouldn't be any good anyway even if it wasn't.
I have a record-route at the beginning of the script which is also recording the wrong address but then that makes sense and is jsut a problem with my script. So is ser using the source address recorded by record route, and how can I work round this?
