Hello. First post so please take it easy on me

My network is setup like this.

*modem* - Dlink Voip Gateway/Router - Netgear Wireless/4 port Router - 10 port switch - computers

As it currently sits, the Gateway creates a network of 192.168.15.1.
That gives the Netgear Router an IP of 192.168.15.x.

Then the Netgear router creates another network of 192.168.1.x and the 10 port switch plugs into that to provide all of our computers in the house, both wired and wireless with network connectivity.

Now my problem is that i dont know how to forward the ports in the gateway. because its on two different ip ranges, how should i go about doing this?

Does the port get forwarded to MY ip? or to the netgear routers IP?

Ive opened the ports to MY ip, then went to SheildsUp! to determine if they were actually open or not, but they came back as "stealth"

So what gives? does anyone have an answer for me?

Thank you

Ben

I'd configure the VoIP gateway to put the Netgear router in the DMZ, thus avoiding any port forwarding in the D-Link unit.

 

[6gSI]

so all port forwarding would be done through the netgear router in that instance?

Edit : Looking through the options available in the DLink unit, i dont see a DMZ option or anything similar. Unless Pass-thru mode is the same thing. I have enabled passthru, and now i get a "closed" port status when i goto shields up.

the ports that i want open are mapped to my ip from the netgear router, and the same ports are mapped from the dlink to the netgear router's ip.

I'm not familiar with that D-Link VoIP gateway, but it should have a DMZ option.

The make/model and a link to the manual would be helpful. :smile:

Yes Yes, forgive me. Its a DLink DVG-1120M. The manual can be found at http://min.aesthetiks.net/filehost/dvg1120M_manual_110.pdf

Also, the Netgear router is a WGT624 v3.
Its manual can be found here. http://kbserver.netgear.com/pdf/wgt624v3_ref_manual_25Apr05.pdf

is setting a gateway into bridge mode the same as setting a DMZ?

 

[johnwill]

Check page 11 of the DVG-1120M manual, you want to put that device in bridge mode. Then the Netgear router will have a direct link to the public IP address. You don't really want the DVG-1120M acting as a router.

Ok, so i tried this earlier. I set the Gateway to bridge mode. But that caused my phone not to work and me not to have an internet connection. Also, after setting bridge mode, i turned off the dmz option on the router and lost the ability to communicate with the gateway.

So im not sure that i can go about doing it that way. if thats the only way to go about it, then i guess im kinda screwed.

I still just dont understand why the ports are showing stealth.

Well, the DVG-1120M is a router. Plan B would be to do the port forwarding in that unit and setup the Netgear as a wireless switch, see the following tutorial.

Connecting two SOHO broadband routers together.

Configure the IP address of the secondary router to be in the same subnet as the primary router, but out of the range of the DHCP server in the primary router. For instance DHCP server addresses 192.168.0.2 through 192.168.0.100, I'd assign the secondary router 192.168.0.254 as it's IP address.

Note: Do this first, as you will have to reboot the computer to connect to the router again for the remaining changes.

Disable the DHCP server in the secondary router.

Setup the wireless section just the way you would if it was the primary router, channels, encryption, etc.

Connect from the primary router's LAN port to one of the LAN ports on the secondary router. If there is no uplink port and neither of the routers have auto-sensing ports, use a cross-over cable. Leave the WAN port unconnected!

This procedure bypasses the routing function (NAT layer) and configures the router as a switch (or wireless access point for wireless routers).
