Attempting to setup a FreePBX v220.127.116.11 server and have some topology questions.
Router1 interfaces (Dual WAN Zywall Router):
WAN1 IP = 65.175.x.x Cable Modem
WAN2 IP = 64.223.x.x DSL Modem
VNET1 = 192.168.1.1
Router2 interfaces (Cisco 1721):
WAN = 192.168.1.2
LAN = 18.104.22.168
So in a nutshell i have a primary router with two external IP addresses which NATs to a second router i then have all of my PC's connected to the internal interface of the second router. what i want to do is run FreePBX with an external interface and an internal interface. The external interface should reside on the 192.168.1.x network by connecting it to a VLAN1 configured port on router1 (between the routers so that the SIP trunk traffic is not passing over my second router). The internal interface should be on the 220.220.220.x network in order to provide a connection to all of my SIP phones and soft phones on the PC's. With this setup no VoIP traffic should be passing over router2 at any point.
To simplify things for now i have forced all SIP traffic over the DSL connection and left the cable modem connection out of the mix so that we are only dealing with a single external IP (64.223.x.x).
Is this a viable configuration?
From what i have been able to dig up this will not work since i can only bind SIP to a single address, is that a correct statement?
I have some more questions but lets start with this since it will dictate which of my other questions still apply.
