Help with Motorola VT1005V

My Motorola Vonage adaptor used to be wired by itself into one of the ports of my Linksys router where it worked perfectly. I recently connected a PC to the Motorola adaptor and noticed that it would give that PC an IP address of 192.168.102.100 while the rest of the equipment in my network had an IP of 192.168.1.XXX. Since I needed to include that PC in my network, Vonage said that the IP address provided by the Motorola box could not be changed and my only resort was to change the IP range of my Linksys router to 192.168.102.XXX so that the PC hooked up to the Motorola adaptor could be networked.

I've now configured the network to use an IP of 192.168.102.XXX but now the Motorola adaptor doesn't want to connect!! Naturally, the PC connected to it doesn't have a connection either.

Could someone give me some instructions on how to get the Vonage box (and my PC's connection) working again??

Do I tell the Motorola box to obtain an IP address automatically or should it be manually? And should I use the router's DNS settings or have the Motorola box do it automatically??

If you hook something downstream of the Motorola, you are putting that machine in a separate network. You need to plug the PC into your regular Linksys router, not into the Motorola, if you need the PC on your regular network.

Even if I've been able to put them together in the same subnet (192.168.102.XXX)?? It should work, right??

But first and foremost, I need to get the Motorola working again. As it is, it doesn't even want to connect now....all I get is two blinks and that's it.....

Reset your Linksys to 192.168.1.1 and your Linksys network to 192.168.1.x

Reset your Motorola (if it isn't already) to get IP from your Linksys.

Your problem is that the Motorola is offering NAT services and I don't think there's a way to turn that off. So anything hooked to the Moto will be in a different network from your main network. Hence the 192.168.102.x business on the LAN side of the Moto.

However, from the Linksys router, the Moto will have a different IP address assigned to it by the Linksys. This will probably be 192.168.1.100 if it's the first device powered up, but not necessarily. It'll be in the range of 192.168.1.x anyway.

All of your other PC's, if plugged into the Linksys, will also get addresses in the range 192.168.1.x

Any PC's plugged into the Moto will be assigned an address by the Moto. From what you've described, that will be 192.168.102.x, and they will access the Internet by routing through the Moto, then the Linksys. However, since they are on a different network, they won't be able to "see" any computers attached to the Linksys, though they SHOULD be able to get out to the Internet.

Regardless, I think you want a configuration like this:

Cable/DSL Modem -> Linksys WAN

Linksys LAN1 -> Motorola WAN
Linksys LAN2-4 -> PCs and other network hardware

Motorola LAN -> (empty)

Motorola set to automatically receive address from Linksys.

Hope this helps out. If I haven't been clear, let me know and I'll sketch it out.

Quick generic diagram:

"Primary Router" is your Linksys

"Vonage Router" in your case is the Moto. The Moto may or may not be capable of remote administration. If I recall correctly (and I've never had one...) you administer that through the phone, right?

If the Motorola will always give whatever's downstream an IP address with a different subnet then I'm out of luck....I guess I'll do it the way that I used to....with a very long phone cord.... Lol

Unfortunately, I have yet to see one of these devices that can allow passthrough without performing NAT. So sorry.

You CAN, however, pick up a cheap switch and put it in front of the Moto wherever you want the Moto to be, then plug in your PC or other device, so it would be:

Modem -> Linksys WAN
Linksys LAN 1 -> SWITCH UPLINK

SWITCH LAN1 -> Moto
SWITCH LAN2 -> PC

You can also, if you can disconnect your house wiring from the telephone company (assuming you do NOT have DSL, of course!), simply plug the Moto into a wall jack and all the other wall jacks in your house will instantly have Vonage service.

Just be sure the wires coming in from the telephone company are completely disconnected from your inside wiring, and that there is zero voltage on the wires inside the house from any external source, or you will fry your moto. Zap.

The solution to your issue is to switch the Moto to bridge mode. Change the IP range on your router back to what it was. On the computer connected to the Moto, open a browser and connect to http://192.168.102.1. On the Advanced tab, uncheck DHCP/NAT, save the change and reboot the device. Everything should start working now including the computer connected to the Moto.

Once he's done that, how does he access the Motorola's page? Will it still be 192.168.102.1?
