I have been considering getting a new router for about a month now. I am currently using the router my internet supplier provided but after looking it up basically everyone says not to use the router that is given to you. I also managed to mess up my port forwarding too. I just watched a few YouTube videos and thought that that was all I had to do. I actually never knew I needed to set up a static IP and now my ports are all messed up. Can someone please tell me that I get a new router will it reset my forwarded ports and fix the problem?
 
Yes it will! Forwarded ports, private IP's and other related settings are saved on to your router. So getting a new router will result in losing all these settings.

PS, Dont forget everyone will have to re-connect to your network!
 
Reehog,

Let me tell you about my situation it will help you.

We originally had a comcast "gateway" this is the modem and router in one unit. Our problem was that we sometimes have 8 people in our house and the router would not handle the amount of traffic, it would fold up and crash in no time.

So I did some digging and found the users manual for it. Our gateway and ISP support something called "bridge mode". Basically what this does is turn off the router part of the gateway and let the internet pass straight through with no NAT. NAT is Network Address Translation, what is does is simple.

You get an IP address from your ISP right, but how can several computers on your home network use the internet then ?

Let's say your PUBLIC IP address (the side of the modem that "faces" the internet, the public side) is 57.181.23.45. Obviously if all the computers tried to use that there would be a traffic jam. What NAT routers do is first give every device a PRIVATE IP (the side that "faces, is internal to your network) such as 192.168. 0.50. Other machines usually get similar numbers such as 192.168.0.51, 52 and so on. these are handed out by the router by default (unless you monkey with settings. Your devices are usually set up to ask the router for the whatever numbers it has available.

So NOW each device has it's own 192 number, and the ISP router a.ka. "gateway has it wan address. The router keeps track of the public and private IP addresses, and when you send data from computer one, it tags the data you sent with extra info identifying which computer it comes from. Computer 2 gets it's packets identified with a different tag and so on. These packets go online and some data comes back in, this data has the information in it as to which IP computer initiated the sending and so the router sends it to that one basically. (In some cases it's sent to everyone, but the other computers ignore it because of the tags, but that is beyond all this)

The point of all this is that your ISP supplied box is doing NAT and if you plug a router into it, the router does NAT too (it NATS, the already "NAT'D stuff) and that's bad. It makes things work poorly or not at all.

So you either buy a router that works with your ISP and completely dump the 1st one, OR you may have a router also, or just buy one. you then put your ISP box into "bridge mode", this turns off the NAT on their crap box and usually the wifi as well but leaves the ethernet port(s) alone and the internet goes right through. Then you just hook the cable from the ISP crapbox to the wan port on your router. The router does the heavy lifting and won't cave in if it's a good brand.

The thing is is you don't need a static IP either. New routers come with what is called DDNS built in. What you do is you go to a DDNS provider such as mine (no-ip.com) and get a "hostname" like REEHOGGAMING.DDNS.NET for example.
You put this info into your router, and then the router tells no-ip to link the PUBLIC IP address it has to the REEHOGGAMING.DDNS.NET hostname. When your router gets a new IP from the ISP (such as every 2 days, or when you reboot the ISP box, your router then tells no-ip.com that the PUBLIC IP address the ISP box has is changed and updates it so REEHOGGAMING has the new address.

You just have your friends use the REEHOGGAMING instead of the IP and they can find your server, or game or what have you all the time. You do need to re setup your port forwarding, but only once because you just tell it to forward to and from from your new routers " gateway" address. This stays fixed like 192.168.0.1. This is the permanent IP of your router as far as all your computers are concerned. from there the router handles what to do as far as translating it to the public IP.
Your "forwarded" ports don't change this way and if you need a "static" IP the DDNS server takes care of it. If you don't need a static IP your forwarded ports STILL DO NOT CHANGE because your router always uses the same gateway IP and tags your packets during NAT.

I run a server for teamspeak like this all the time. Also if the router you buy or add on does not have DDNS capability, there is a program you can install on each PC that runs at startup and it does the IP address to hostname updating, so you still have the same benefit as if it's in the router.
