I have dynamic IP address ?

post #1 of 13
Thread Starter 
I'm having trouble opening ports for games. Is this because I have dynamic IP address? This sux!! I didn't have dynamic ip address , ISP must have changed it recently.


What are the good and bad things of dynamic IP?

Trouble opening ports ≠ dynamic IP address.

Have you changed the settings in your router to allow the ports?

It won't matter with a router if your ip from ISP is changing. Your local ip will remain the same in your network. Its when ISP change up DNS server addresses what screw you up.

Good things- it's untraceable. Meaning the only ppl who can hack you, or monitor your network activity, are the ones on the same local net.
The bad things- stuff won't work. For example, you can't host Multiplayer over IP, as some games demand (Fifa, some older versions, don't know about the recent).

What are the good and bad things of dynamic IP?

Your ISP givin you a dynamic IP has nothing to do with your port forwarding.

You need to make ur computers IP static or reserve an IP allocation in your router for local network, then you can open the ports for your games,


Are you trying to host a game server or just play normal multiplayer games

You are confusing your external ip given by your isp and your internal ip given to each computer via your router.

Your router will assign each pc on the network a ip address and this ip can change (making it dynamic) You need to set the machine you are trying to forward ports through to stick to one loacal ip. This is easily done in the network settings.

After you have your machine set to static ip you can then forward your ports in your routers settings.

why do you even need to open ports? doesnt upnp do this for you

Ports forwarded to your internal LAN will still be forwarded if your WAN IP changes. It doesn't matter what the external IP of the device is, the router will perform the forwarding on any traffic coming through that interface.

As others have mentioned, you'll need to give the machine you are forwarding to a static IP address. That can by done by configuring a static IP directly on the adapter (Windows networking) or by setting up a DHCP reservation on the router. Remember to choose an IP address outside of the DHCP scope to prevent address conflicts.

What? Maybe you should take a course in networking..

That being said, once you forward on your router the same port forwarding will still be applicable if your WAN IP changes. You would simply have to give your users your new WAN IP if changed. To circumvent this you could run Dyndns with the automatic updating client on your PC, then you will always have your dyndns address forwarding to your WAN IP.

If your LAN IP changes on your box, forwarding will also fail to function. Therefore it's generally a good idea to set a static IP outside of your DHCP range on the box you want to be a server.

Make sure there are no software firewalls present that may be preventing connections on the server itself.

Ok,networking is not exactly my thing, but how would an external intruder hack your PC if only 1 external IP is visible (server's)?
