Bridged Comacst Modem/Router to D-Link Router now MicroCell not working
New to Comcast as my IP, bought my own Arris Modem Router with phone line ports, then Comcast loaded their firmware on to it so now logging in to it, it looks just like a Comcast router. A little background, When I first set up Comcast gateway, I set the Firewall settings high can't remember the term or checked box. What happened when I did it though is that it blocked my Micro Cell from working, I changed it to a lower setting and then the Micro Cell worked fine. Then I decided I wanted to use OpenDNS filtering service, which Comcast won't allow in the settings of Gateway (modem/Router), So I bought a new D-Link Model DIR655C1, switched the Arris/Comcast Gateway to bridge-mode, which then only gives one functioning Ethernet port, #1 port (or so I was told) That functioning Port , Port #1 hooks to the D-Link router Internet Port. I then have my MAC, Printer and Micro Cell all wired to D-Link router by Ethernet. The Micro Cell is in the same spot when it was working with the Comcast Gateway, all the lights show it's working fine and all cell phones can see it. It's just won't allow a cell phone that is connected to the Micro Cell to make or receive calls. This is similar to what happened when I set the Firewall setting to high on the Comcast router. I searched the settings on the D-Link but can't find any where to reduce firewall protection, so it may be something else. Thanks for any help, I'm by far an IT guy, but my wife thinks I am, so please help me keep the Lie going.
