I've tried putting my DIR-655 behind my Vonage VOIP box/router and can't get it to work. The setup I want is:
Cable Modem -> Vonage -> DIR-655 router.
I have Comcast Internet with a dynamic IP address. The Vonage box includes a basic router, but I want the Vonage box only to handle VOIP and all other functions, including DHCP, to be done by my 655.
The Vonage box's LAN IP is 192.168.15.1. I turned its DHCP server OFF and set up DMZ for 192.168.15.2 -- which then is supposed to be the LAN IP address for the 655. The Vonage router has no function for assigning static IP addresses. It's simply DHCP server ON/OFF.
Also, the Vonage box can set DMZ only within 192.168.15.* -- that is, only the last number is selectable.
Problem is that, when I plug everything in, my D-Link router is stuck "Connecting" -- that is, it seems it is unable to communicate properly with the Vonage router.
At present, the 655 is set: "My Internet Connection is: Dynamic IP (DHCP)".
Is it supposed to be "Static IP". If so, I can't figure out what to put in the fields at the bottom:
IP Address :
Subnet Mask :
Default Gateway :
Primary DNS Server :
Secondary DNS Server :
Any suggestions for how to do this properly?
