Ok. I just got my Motorola ATA and plugged it in behind my linksys router. Works great after forwarding the appropriate ports. However, I know that my call quality will be affected once the other 2 users on my home network begin to dl/ul files, so I want to put the ATA in front of the router as to enable QoS. Well, I tried that, and everything died.

I have a static IP from my DSL provider and as such I have the static information entered on my router. I entered this very same information on the ATA configuration (IP/Subnet/Gateway) and the flashing green light eventually became solid. But, get this! As soon as I plugged in the router's WAN port to the ATA PC port, I go back to the 4 blinking light pattern! I don't understand what's happening.

I didn't change anything on my router, so it's still configured for the static ip as is the ATA. I disabled the DHCP/NAT on the ATA hoping to have the ATA act as a pass-thru, but nothing. If I don't plug the router into the ATA, Vonage works great. The instant I plug it in, the system dies. It doesn't happen when I directly connect my PC to the ATA. Odd, huh?

Anyone have a clue as to what's going on? I'd really like to have the QoS functioning, but I'm kinda worried that my ATA is possesed and doesn't like to have my router plugged into it.

Thank you in advance!

Most likely, the problem is that your router is now on an internal network after the ATA, but has a static IP address set to an outside IP. The fact that the ATA and the router have the same IP address may be confusing the ATA. Try changing the router to obtain a WAN IP address automatically (from the ATA) and see if that helps.

My ATA is behind the router so this answer is not from experience. Judging from the description of your problem, it just makes sense.

Good luck!

I think the problem is even more basic than that. You have both devices configured to use a static IP address, but more importantly they are configured to use the same static IP address! This means you have two devices on the same network with the same IP address which is the number 1 networking no-no. Configure the router for DHCP instead of static and you should be fine.

The way I have my network setup at home is that all the computers have a 10.0.0.* address. I assume by changing my router to something like 192.168.102.* I would have to change the private IPs of all the other devices, no? Also, would I set the DMZ host on the ATA as the new IP of my router, say 192.168.102.2? I'd still like to be able to use the DMZ host feature of my router since one of the computers on my network is usually the DMZ host.

I think you're confusing your internal LAN IP addresses with your WAN IP address. They are unrelated. If you configure your WAN IP address to DHCP, the router will get the WAN IP address from the ATA. The computers on the other side of the router will have the same IP addresses they have now, unless you change the LAN configuration of the router.

Good luck.
