Expose device to outside network on Belkin Router

Dec 21, 2014 11:41PM PST

I have a Belkin N600DB router that runs a smaller secondary network. One of the devices on the secondary network is a computer that I use for retro gaming and running a few minimal servers. I want to expose it to the outside network so that I don't have to port forward every port t hat I will ever possibly use. To add to that, my secondary router maxes out at 20 ports. My primary router is Netgear if that is any help.

While a nod to the DMZ entry is my first idea.

Why isn't this a LAN? That is you can use second routers (I'm guessing your setup) as a WAP.

What DMZ? I have no reason for one
Dec 22, 2014 12:53AM PST

I'm not certian what you mean. My setup is I have a netgear router hooked up to the cable modem. From there, I have a variety of wireless devices, a tower, and my secondary router. My secondary router is plugged into the primary through an ethernet cable with no configuration beyond a reserved IP address. From there the secodary router branches to my other computers, none of which have wireless, and are in the next room.

Then I take it this is your first networking challenge.

Since you can't use the DMZ solution, forget the WAN port of the second router and use it as a switch to create a LAN.

All skill levels arrive here. I start at a level based on guessing where you are in the skill/learning and may guess badly. Also, unlike tech support I expect folk to get out and push (research what things are, check the product manual or at least supply links to product manuals when they can't read them.)

Forget the WAN port?

If I disconnect the WAN port on my Belkin, than how will my box connect to the internet? I don't understand what you omean by using it as a switch.

Use it as a WAP or switch.

It's simply you are pretty new to networking (no big deal, we all start somewhere) so you can't use the DMZ, port forwarding is limited so let's turn it into a WAP or Switch.

It's all of two steps in the second router.

1. Turn off DHCP in the second router.
2. Move the cable from the WAN port to the LAN port.

It's now one LAN and all will work.

Quick Confirmation

You mean to move the cable from WAN to LAN on the second router, right?
I'm pretty sure that's what you mena, but I can't be certian. And from there, what do I do with my computers, how do I configrue them?

Sorry.

I fear you might have missed one word. As to it computers, all sounded like they were DHCP so about all we do is nothing or reboot them.

Well, if it's that simple...
Dec 22, 2014 10:51AM PST

If it's as simple as "Turn off DHCP, Switch Cable," tell that to my router. It's blatently refusing to let my box online except in a standard setup (modem, router, other router, computer)

And right as I say that...

It just suddenly started working. Is there an emotocon for that it's-right-in-front-of-my-face-but-I-still-can't-believe-it look? Netgear Genie shows two new devices, and I know my box never played that particular youtube video before, which eliminates browser cache. I don't quite understand how, but that worked. I'll have to do more research...

I wish I had that up front.

I can selectively block an IP from the internet on most routers. Good you got it working anyway.

I can also block IPs
Dec 23, 2014 4:49AM PST

I can tell either one of my routers to block an IP. Both Belkin and Netgear call that a "Parental Control"

Okay...
Dec 22, 2014 4:11AM PST

I'll take your lack of response as a "yes you idiot, I mean on the second router." Though I tried that afte you posted this, and also tried a few tricks involving the access point mode. Neither of those worked. After plugging from WAN to LAN, how do I configure the Belkin and the Netgear

That's why I numbered the steps.
Dec 22, 2014 4:16AM PST

Because changing the second router after the cable move can test a new networker's skills. I decided to pare it down to just 2 steps. Normally I'd add one more step but here, you need time and experience to hone your skills.

I don't mind repeating replies.
