    How can I run more than one PBX behind a single static IP and a DDWRT router? I have a Windows Server 2003 in my arsenal, plus two sperate boxes, one for each PBX.

    I need to make sure that SIP, RTP, and TFTP traffic is properly routed. And I also need to access the web admins easily from pbx.domain1.com and pbx.domain2.com. In addition, I need to be able to access a sharepoint site on the 2003 server at domain3.com.

    Please help.

    With NAT you can use IAX2 protocol (you can change 4569 port to 4545 by example and nat 4545 to 4569 on the second IPBX.
    I've done tests, it's not possible to do the same in SIP. STUN server seems to be mandatory.
