Consider the following scenario: UA---NAT---Proxy1---Proxy2+UsrLoc User agent UA is behind NAT which send a REGISTER request to Proxy2 but was instructed to use Proxy1 as the first hub. Which of the two proxies should rewrite the contact header. Note that Proxy1 does nothing but to forward all requests to Proxy2, something like: Route[0] { check (max_forward_header & message_len); record_route(); rewritehostport(proxy2:port); t_relay(); } Zeus Ng _______________________________________________ Serusers mailing list serusers(a)lists.iptel.org http://lists.iptel.org/mailman/listinfo/serusers
