I have not worked with Asterisk or SIP at all, but it sounds like what you need is a combination of sipproxd to get past the NAT issues and some sort of load balancer like SER or Ultra Monkey to round-robin (or whatever) the two Asterisk servers. So that you'd wind up with:
asterisk1 -* +- SER -- sipproxd -- pfSense asterisk2 -* On the pfSense box you'd do a 1:1 NAT of your public IP to the internal IP of the sipproxd server. I'm not sure how it'd work exactly if sipproxd was on the pfSense box. ----- Original Message ----- From: "Chris Buechler" <cbuech...@gmail.com> To: support@pfsense.com Sent: Friday, January 14, 2011 12:36:39 PM Subject: Re: [pfSense Support] Is it possible to Port Forward same PORT to TWO servers? pfsense + TWO Asterisk servers and NAT On Fri, Jan 14, 2011 at 3:34 PM, David Burgess <apt....@gmail.com> wrote: > On Fri, Jan 14, 2011 at 11:55 AM, Bruce B <bruceb...@gmail.com> wrote: >> Hi Everyone, >> I am facing a dilemma here.
