In my Elastix configuration the server has two NIC's. Only one was configured at installation with a private IP. 1) all phones register at the IP of the LAN interface. 2) router forwards all trunk connections with 1 to 1 NAT to LAN interface. I would like to give the second NIC a public IP and have the trunks register there, and keep the IP phones registering on the LAN NIC. When I tried to do this before, I couldn't get calls to complete inbound or outbound. Is there an easy way to set this up?
