I have trixbox running on my home LAN on the same ESX server, which is my old pbx system. And I didn't map any port on the router and I use google voice, freephoneline, voipcheap, etc and they all works fine. I do need to setup the external ip, my local lan settings on *, but that's it, nothing relate to the router. I keep digging. If someone have the answer, pls let me know.

Well, there is no "the RTP port" -- there is a range which is quite large by default.
I mean setup a rule to block the port, not point it somewhere else. Though I guess you could point it to a black hole (IP that is never assigned).
Why/how * works, I dunno. Maybe someone else can answer that question. I don't see how to handle RTP data properly through a firewall without support for portmapping initiated by FS (using upnp or nat-pmp) or having a SIP ALG running on the firewall.

Hi Rupa
Do you mean create a port map on the router to map to other ip instead of FS?
update: That seems working. But do you think I can just turn off the auto-nat and map the rtp port out to get it working? Which way is the best? In the asterisk, I don't even need turn on upnp and don't need to map the port and it works fine behind the router, even those ATAs, normally you don't need to map any port on the router and they just register from isp and works fine with router(non UPNP & UPNP), why FS need do those extra step? I try to find the answer in the WiKi but cant find the explaination for that.
Thanks
Alex

Hmmm... ?I didn't put anything in the nat_map code to allow some parts of the sofia profile to participate in the nat mapping while others do not.
Brian, do you have any ideas?
Alex, I'd suggest just blocking ports 5060-5080 on the firewall. ?The port blocking *should* take precedence over the upnp maps.

Hi All
Just don't want to open these port to the public, all my extensions are in my LAN. If I disable upnp, the outside sip register is not working, I mean no sound. How to disable the auto-nat publish 5060-5080 on the internet?
Thanks
Alex
