netopia 3347-02-1006L

I have 2 of these and having a moment today, I got them up and running as a modem/router...
No problem. But where I am having some confusion is setting up a port forwarding, they call it pin hole, for my voip adapter. All my ATAs have a static IP so the router can forward the entire range of ports with no problem on all my boxes. I have 4 different routers and no problem doing this, but with the 3347 and the pin hole scenario, I haven't yet conquered it.
Even though I have telnet activated on my XP, I can't get into the Netopia, and I have full GUI access with no problem, but can't get the hang of setting this up.
Specifically I need the router to port forward UDP (5004 to 65000) pointed to 192.168.1.150.

Any help would be appreciated. Thanks..

You need to first go into Expert Mode.




Then go to Configure/Advanced/Pinholes to enter the port (range) that you want to forward.




Here is an existing pin hole that I have setup in the 3347 that I use as my backup connection. It is only a single TCP port, but a range of UDP ports should work just as well.




After creating a pinhole, you then need to click on the "!" icon to go to the save and restart menu. The pinhole will not be activated until you do that step. I can't show you a screen shot of that menu because the 3347 that I have access to is currently in use by multiple users, and I don't want to reboot it.

Telnet mode should have been enabled by default, but you can go to Configure/Advanced/InternalServers and make sure that the proper port is set for telnet access.




If you have already tried all of the above steps, the 3347's SPI firewall may be blocking you. Try going to Security/Firewall and checking the ClearSailing setting.

I'm not 100% sure, but I don't think you can forward a range of ports that large and/or to that high a port number on that router.

You are right about the high port number. Since it is late in the evening, and there were only a couple of users on-line, I tried the OP's port range, and it barfed on the high port number.







However, the OP should be able to put the device needing the high port number into the 3347's DMZ (called the default NAT server), and not have to use port forwarding (assuming that the device has its own firewall and putting it into the DMZ would not be a problem).

Thanks, guys....

I was familiar with all the things you both indicated and the port range refused for me as well.
I've never been comfortable using the DMZ for my setup.
I did have it set to clear sailing as the SPI firewall setting on any of the routers tends to interfere with the Voip from time to time. I use a 3rd party firewall with no problems.

I have never had a good result using a combo modem/router, especially with Voip that I have used exclusively for many years now.

With all my other modems and routers, I have no problems. For me, the Voip works flawlessly when I assign a fixed IP to the ATA and have the router point to it for the full port range indicated..

I guess like we all tend to do with spare time...try to conquer new frontiers and reinvent the wheel. My shelves are already cluttered with devices that I'll never live long enough to use. I will put the 3347s along with them.

Thanks once again....

Generally speaking separating the modem and the router are the better approach. This allows you to buy a modem once, put it into bridging mode and forget it until it breaks.

Then you can change routers until you get happy. I would imagine that there are some pretty strong SOHO type units that can handle just about anything. But for me I have gone with things like m0n0wall or pfsense running on rather meager PC type hardware or specifically for firewall type headless x86 units.
