How do I setup a DMZ host on a dsl-2540u router for VoIP applications. I do not seem to be able to successfully setup vistual servers to open-up the needed ports on the routers (UDP/TCP ports 5060-5061, 16000-17000 and 40000-65525) nor do the STUN server settings on my ATA have an influence on the fact that all calls get dropped after 30 seconds. By the way I use a SIPURA SPA3000 ATA. I guess the DMZ host might be the only hope left.

Contact your ISP immediately- the issue you have is called no sync. Basically with the DSL led going completely off- that would point to a bad modem, however the fact that you have no sync otherwise indicates your DSL provider may need to service your DSL line.
Make sure you download the correct firmware for you Hardware.
Usually you can login on your browser to you router and go to the management section to check for firmware updates and select that button and it will download and install the firmware. On some models, you have to go to the D-link web site and look for firmware updates for your router. Always check what you current firmware you have installed and check the version of you router modem hardware (A, B, C etc). Then you can manually download the firmware (usually in a ZIP file), open the zip file, and then using your browser connected to the router look for Update Firmware. You will have to go to where (folder) you saved the downloaded update and select that file. It is recommended that you update using a LAN connection and not a wireless connection.
1. Check for current anti-virus before doing step below. 2.Check firewall allowances or permission to be sure game is allowed 3. Try "port forwarding 4. Check the game / verify ports need for multiplayer gaming. 5. Please forward all ports UDP/ TCP To gaming computers IP address.\ 6. Log in to router and place gaming computer in to DMZ. 7. When done gaming disable the game in the DMZ.
Here are some options with that router. Some online games and videoconferencing applications are incompatible with NAT. The WGR614 router is programmed to recognize some of these applications and to work properly with them, but there are other applications that may not function well. In some cases, one local PC can run the application properly if that PC’s IP address is entered as the default in the PORTS Menu. If one local PC acts as a game or videoconferencing host, enter its IP address as the default
To set up an additional computer to play games like Half Life, KALI or Quake III: 1.Click the button of an unused port in the table. 2.Select the game again from the Service Name list. 3.Change the beginning port number in the Start Port box. For these games, use the supplied number in the default listing and add +1 for each additional computer. For example, if you've already configured one computer to play Hexen II (using port 26900), the second computer's port number would be 26901, and the third computer would be 26902. 4.Type the same port number in the End Port box that you typed in the Start Port box. 5.Type the IP address of the additional computer in the Server IP Address box. 6.Click Apply
The WAN Setup options let you configure a DMZ server, change the MTU size and enable the router to respond to a Ping on the WAN port.
Connect Automatically, as Required
Normally, this option should be Enabled, so that an Internet connection will be made automatically, whenever Internet-bound traffic is detected. In locations where Internet access is billed by the minute, if this causes high connection costs, you can disable this setting.
If disabled, you must connect manually, using the sub-screen accessed from the Router Status menu "Show WAN Status" screen.
•Disable SPI Firewall
Normally, this option should be Enabled, so that your local network will be protected by the Stateful Packet Inspection (SPI) firewall included in the WGR614. However, certain communications functions like VPN may require turning off the SPI feature.
•Setting Up a Default DMZ Server
The default DMZ server feature is helpful when using some online games and videoconferencing applications that are incompatible with NAT. The router is programmed to recognize some of these applications and to work properly with them, but there are other applications that may not function well. In some cases, one local PC can run the application properly if that PC’s IP address is entered as the default DMZ server.
Note: DMZ servers pose a security risk. A computer designated as the default DMZ server loses much of the protection of the firewall, and is exposed to exploits from the Internet. If compromised, the DMZ server can be used to attack your network.
The WAN Setup menu, shown below lets you configure a Default DMZ Server.
To assign a computer or server to be a Default DMZ server, follow these steps:
1.Click WAN Setup link on the Advanced section of the main menu.
2.Type the IP address for that server. To remove the default DMZ server, replace the IP address numbers with all zeros.
i worked for verizon for two years and I encounter this problem many times,to tell you honestly,its not with you internet connection since if you'll notice,while you are connected to the internet and you make a call or call someone,its interrupted... Obviously,its the phone itslelf,the signal comng from the phone is different from the signal of the internet...thats the reason why you need a modem to convert the signal coming from the phone line to make it work for internet,,,what I suggest is you change the DSL plan from the Dry Loop to the regular dsl with the phone...
