Skip the whole NAT scenario.
Put up an asterisk box with two network interfaces. One interface
connects to the real world on your new IP address from your new ISP.
The other interface can be on the same subnet as the windows box that
you can't change. Set up a SIP trunk to your Windows box.

them for service. Th
Hello,
if the remote side (the public IP side) is capable to do

If the remote side does not support that nat-hack (which
is not SIP standard), than you wil
Is there a tool that will allow me to automatically change sip headers in
