MTA not getting IP behind Router

My setup is Cable Modem --> D-Link DI-604 Router --> VT1005v and PC.

It is set to use a static IP but it's not getting one.

My Vonage is setup as follows with a static IP:

vonage/vonage_status.gif" border="0" />

vonage/vonage_basic.gif" border="0" />

vonage/vonage_advanced.gif" border="0" />

My router is set to give it the same IP, 192.168.102.105, based on its MAC address.

Should I be using a gateway address? If so, which one? My router's LAN IP (the same one my computer is successfully using)? Or what?

The IP 192.168.102.105 is also in the DMZ on my router, so I don't have to deal with port forwarding possibly being an issue.

I have been reading other posts, but nothing I've tried works. I'd appreciate any help.

Thanks

Yes, you need to set the gateway address. Whatever IP you use to connect to your router from your PC is usually it. You also need to specify the two DNS server IPs. The best thing to do would be to log into your router from your PC, and look up both the gateway address and the two DNS servers. This information can usually be found on the status page of the router settings.

Okay, I did the following:

MTA is now using the same gateway IP as my computer, the router's IP
MTA is now using the DNS server IPs the router is using (external IPs. My computer uses the router's IP as its DNS server)

Still no IP on the MTA when I reboot all devices (router, then modem, check the internet connection, the the MTA)

I have two cables in the MTA, one from the WAN port to port 1 on my router, and one from the LAN (PC) port to port 2 on my router. Don't know if that matters.

Also, my router does DHCP, but all devices have a static IP assigned to them based on their MAC addresses. All those static IPs are within the range of DHCP IPs. I don't know if that matters, but some people were saying the static MTA IP shouldn't be in the DHCP range.

Have the MTA obtain its IP from the router. Have the router assign the IP you want it to have based on the MTA's MAC. I don't think your router likes to be forced to send an IP to a device that also wants to set the same one on its own.

Whoich router are you using? Also, don't put your static IPs in the dynamic IP range because if you plug in another machine, your router might give it one of the static IPs if it is down. It will work, but it might break stuff.

There is no need to enable DMZ, and no need to port forward. Also, you don't really want to assign your DNS servers to the ones on your router, your ISP may change them. Just give your MTA one DNS server, your router IP.
