<DIV></DIV>Why not test for RFC1918 addresses? That's what the onsip.org
nat-handling scripts do. A NATed destination is determined by a flag in the
location record and the src ip is checked with nat_uac_test(). It will
give a more robust NAT handling that testing on IP addresses for parts of the
RFC1918 addresses. <BR>The problem has already been solved, why not reuse?
