redirect + swapping of ports

Hi, I am a novice in Freeswitch. I have a provider sending me calls on 5060 port only. I have 2 FS's. Calls are landing on FS1. From FS1, I need to redirect to FS2 (lets assume all calls to be redirected) With normal config's (I had done few config changes in default and public), I was able to get some logs albeit (Proxy Authentication error). This may be because by default internal calls are authenticated. Thats why I swapped ports 5060 and 5080 of internal and external profiles. But I am getting 480 error Any help is appreciated. Thanks. Thanks.
