My problem is with a Motorola VT1005v and Linksys WRT51AB.

When i hook my cable modem to the Motorola (Voice-IP) and then port it to the Linksys; I cannot obtain a DMZ on any of my

computers on my network. Although I have DMZ checked in the Linksys configuration screen. I still am not getting a dmz. THe

reason I need DMZ is to use this P2P program.

Now when I hook the cable modem to the Linksys then to the Motorola. I have no access to the web from any of the computers on

my network.

My question is has anyone ran into this problem?  Does anyone have any ideas to get DMZ working properly with the Motorola +

Linksys? Or have had any success.

Thanks

PS . All computers are DNS.

Are you saying that you connect your cable modem to your VOIP box and then connect that to your router?
If so, I don't know how that works.

The way mine is set up, is I have my router connected to my cable modem. Then I connected my VOIP box to my router. I don't have any DMZ for that. All I did was set the router for DHCP, and it gave the VOIP it's own IP. From there, I set port forwarding for VOIP to the box so I could use my phone.
5060 – 5061 (UDP)
10000 – 20000 (UDP)

I don't know what your configuration is exactly. Hope this gives you some ideas : )

If cannot work that way.

If you make any machine DMZ _all_ traffic will be forwarded to it. That includes the traffic that the VoIP connection needs.
No good. The Motorola just does a smart move by disabling the DMZ function and keeping voice functionality alive.

A better solution would be to find out which ports/protocols your P2P program needs and forward those to your machine.
Security wise this would be a better solition as well.
