Static IP, Port Forwarding not working.

[04nmr85]

I'm currently subscribed to verizon broadband. I have a Network Everywhere router NR041 and a westell 2100 modem i believe. I'm having problems with the port forwarding capabilities of the router. I've entered in the port range and the ip I wish to forward it to(my computer). I apply the settings and it seems to be ok. When i go to http://www.canyouseeme.org/ to check to see if the port is open it doesn't work. It says my ip is 71.X40.X44.1X7 but when I do an ipconfig from the command prompt it says my ip is 192.1X8.1.1XX which should be the correct one because I set up a static ip by going through my connections TCP/IP properties. I'm forwarding the ports to my ip of 192.1X8.1.1XX but i'm still having problems. Any help would be appreciated. I just did a clean install of windows today so i have all the updates and everything. Thanks in advance!

Is the Westell in the bridge mode? If it's in the router mode you have 2 levels of NAT, which will not allow port forwarding. Bridge mode requires that the PPPoE be handled by the router - store your login into the router, not the modem.

I'm not sure what mode the modem is in but I do know that i have entered the PPPoE settings into my routers configuration. It still doesn't seem to be working tho.

EDIT: Thanks GLC, you've given me some direction. When I get home i'm going to try and reconfigure my router and I'll post a reply as to how things went.

[glc]

It may be the *modem* you have to reconfigure, not the router.

Ok so here's whats going on now. I've connected just my modem up to my computer and can connect to the internet just fine. My modem is a Westell Wirespeed(2110). From looking around on the internet it looks like i should be able to get into the modems firmware and configure some options. I should be able to type 192.168.1.1 and get to the configuration page but each time i try that i only get an unable to connect error. Any ideas?

EDIT: I'm not sure if this has anything to do with my problem but when I had the router hooked up my external IP was 71.240.150.103. With just my router hooked up my external IP is 71.254.251.35. Could I have two levels of NAT like you said?

EDIT: Oh, I also found this link with some pretty usefull info http://blogs.msdn.com/gzunino/archiv...29/201213.aspx

With the modem connected directly to the computer, what does ipconfig/all say your IP address and default gateway are?

[04nmr85]

Ok, so I have two connections it seems like. When I have the modem ethernet line going to the router and then the router to my computer I don't have to dial any connection. My PPPoE settings are handled in the routers config. When I have the modem hooked directly into my computer I have to dial a Broadband Connection that I setup with my PPPoE settings in it. When I dial this, with just the modem hooked into my computer, here's what comes up with ipconfig /all:

That first Local Area connection is where I have set up my static IP and everything. The second one i'm assuming is the broadband connection that I set up and dial with just the modem hooked up.

Okay, then the modem is in fact in the bridge mode. There is no logical reason why port forwarding won't work when you use the router, unless you are doing it wrong or the router is bad. This is quite possible, the Network Everywhere series of components is the Linksys budget line, and is not noted for quality.

[04nmr85]

One last thing that I noticed. If I disabled the Local Area Connection when the "Broadband Connection" that I have setup was connected, the Broadband connection disconnected.

[04nmr85]

I don't believe I'm doing it wrong, I followed all the directions I found at portforward.com. Here's a little clip from that link I posted above:

"There were essentially two solutions: either way the modem was acting as a DSL router or my configuration on the D-Link was wrong. A quick search on the internet revealed that a Westell 2100 is a bridge and cannot be configured to be a router therefore setting up PPPoE is required. Being 100% sure that my PPPoE configuration was right, I pulled the heavy artillery: I hooked up the modem output to a computer and ran netmon in promiscuous mode.

I very quickly understood what happened. I saw DHCP and TCP frames. My modem is in fact a Westell 2110 which allows two computers to be connected at the same time (via Ethernet and USB). To achieve this, it contains a little DHCP server and the line negotiation is handled by the modem. I configured the DI-624 to acquire an dynamic IP address (as I would have for a cable connection) and got connectivity."

EDIT: If thats the case, can I just buy a different type of westell modem and use that? Thanks glc for all the help!

[glc]

No, your modem is acting only as a bridge if you have to dial a broadband connection to use it without the router.

Put your TCP/IP back to obtain automatically, hook the router back up, and post an ipconfig.

[04nmr85]

Ok, so I have it set back up to obtain an ip address and dns servers automatically. In my router settings I also have DHCP set up to start it's IP addresses at 192.168.1.100. With that said here is my ipconfig /all info:

EDIT: In my search for a solution I've come accross a couple sites that will tell you your IP and let you test various ports. At canyouseem.org my ip is reported as72.1XX.246 and that when trying to connect to the port i'm trying to forward that it is closed. Also from reading around on the internet I learned that the router has an external IP address and that the 192.168.1.100 address is just my private LAN address. Am I correct in saying that or no?

[04nmr85]

Routing Table Entry List
Destination LAN IP Subnet Mask Default Gateway Hop Count Interface

10.XX.1X.1 255.255.255.255 192.168.1.1 1 WAN

71.25X.2X0.1X0 255.255.255.255 192.168.1.1 1 WAN

192.168.1.0 255.255.255.0 192.168.1.1 1 LAN

192.168.1.1 255.255.255.255 192.168.1.1 1 LAN

Ok, so theres my routing table entry list as listed in my routers static routing configuration page. I know what the last two IPs are and I know what the second ip is, my routers external ip address, but i'm not sure what the first ip is. Could this be the ip of my modem?

[glc]

Hmmmmmm. Okay - if you connect the modem directly to your nic and set TCP/IP to automatic, does it pull an IP address or does it just autoconfigure to a 169.254.xxx.xxx address? If it's pulling an IP, it's not in the bridged mode and you have 2 levels of NAT. The hard part is going to be figuring out exactly how to put the thing in the bridge mode, which is what you have to do to forward ports with your router. This will necessitate the PPPoE login be stored in your router.

You can try running an ipconfig/all and noting the default gateway - if it's 192.168.x.x or 10.x.x.x, browse to that IP and see if you can get into the modem configuration. Some Westells require external software to reconfigure it.

[04nmr85]

Ok, so I've hooked just my modem into my computer. Westell has a "Modem Browser" program that i've downloaded. It basically just shows detailed information about your modem. On it's "Configuration" tab it has an area labeld Modem Communications. Under here it has two ip addresses: Multicast IP Address to send data to and Modem IP Address. I tried typing in the modem ip address in firefox and IE but it did nothing. Then on the last tab called "PVC" it has a little drop down selection box labeled Modem Type. It's disabled but it says that it's a bridge. Ideas?

[glc]

What does ipconfig/all say?
