I have 5 computers on my network.
4 of them are mine and my brothers.

On 3 of they computers i can port forward but on 1 of them i cant.

On one of they computers i was hosting an online server for a game called "Minecraft". I recently got a new computer and wanted to host it on that.

I port forwarded on the computer i was running it on already and it all worked fine, but when i tried to port forward on this computer it didn't do it correctly. I tried multiple times but it still wasn't working.

When i tried to choose the computer to port forward, it told me all the computer on my network except this one.
My network name was KYLE1-PC but it didn't show up as this.
Instead of KYLE1-PC it showed up my MAC Address.

I clicked that as the computer i wanted to port forward but it didn't work.

But i was wondering why it was showing up my MAC Address instead of KYLE1-PC.

I can run it on the computer it usually does but i think the computer that i already run it on is coming to an end so i need this to work.

It lets me port forward it but after i do port forward it won't let users join my online server.

I know how to set it up so i didn't do it wrong.
I just want to know why it wont work on this one computer but it works on any other one.

Please reply ASAP and i will be really thankful if your advice works.

Have you checked the firewall settings on that PC?
 
Port Forwarding is a function of the firewall\router attached to the PC, not really of the PC itself. It allows certain ports to the PC to be exposed to the internet as though the router\firewall did not exist. Occasionally useful for gaming, although MineCraft doesn't need it.
Interesting first post on a cycle forum tbh

Regardless, This PC, how is it connected to the internet, via a router? Does it have a software firewall?
This kind of problem is normally related to settings of the software firewall...<clue>.

As you correctly indicate, port forwarding is a function of the firewall/router. However, the PC must have a static ip address otherwise it would be impossible to port forward to the same pc all the time. If the PC has a dynamic IP address ( TCP/IP) settings = automatically obtain an IP then the router will assign different ip address, depending in what order the computers connect to the internet.

So make sure the pc has a static ip address and that address does not conflict with other clients
Make sure you setup port forwarding to the correct ip address
Make sure you define a firewall rule that covers that ip address or ports (depending on the router )

For "will" screw up, read "may" screw up. Some dhcp servers remember your mac address and attempt to give you the same ip address as you had last time you connected

My two routers do that but you have to manually lock the client to a particular IP

This is the way I have always sorted out port forwarding.....

Let the router assign ip addresses from a pool of 50 addresses that begin 10 addresses from the router. The first 10 addresses in the subnet are used by the router, printer, port forwarding, etc.

So for example if the router has ip address 192.168.1.1 then the dhcp is set to start at 192.168.1.11....
192.168.1.2 ...192.168.1.10 if for static ip that you might need ie, port forwarding,


This site has instructions on how to configure most routers for port forwarding.

How do i change to a static ip address ?

And i dont think it has anything to do with my firewall.

Try explaining what i have to do as easily as you can because if i cant get this to work then bye bye goes my server.
 
If 4 out of 5 are port forwarding without problem then it's not the router.
Does this PC have the same OS as at least one of the other PCs and if so what is the
firewall you are using as for instance if it's Kaspersky then there's a separate internet
blocker that caused someone else problems connecting across their network so check
what other stuff is enabled.
