Portforward question

[priv4cy]

My router is Innbox v45, yesterday i somehow i portforwarded it and it worked, now it won't work. I'm using it for a minecraft server. I don't know if im doing it wrong, can someone walk me thru it?

Your server needs to have a static IP address, so it won't change. You can set that quite easily within the network settings of the OS.

 

Afterwards you need to enable port forwarding for that IP address within your router.

You need to select the right protocol (in this case TCP) and port and forward all incoming trafic to that IP address. Depending on the router, the settings can look quite differently.

 

If you want more help, post a screenshot of the forwarding rule you enabled, but don't show your external IP address.

The Server IP address is of course the IP address of your minecraft server. So there you put in the IP address that you assigned manually to your server.

You didn't need to block that off, since it's a private IP address. IPs that start with 10. 172. or 192. are private IP addresses.

Anything else are public IP addresses, which you shouldn't show publically, unless you know what you're doing.

 

Anyway, back to port forwarding:

All the fields that say port should be the same in this case. That's were you put in the port that your MC server uses. It's either a standard port that has been assigned to your MC server automatically, or you've set it yourself.

 

TCP is the correct protocol.

Some other services might use the UDP protocol, for which you'd need to set up a seperate port forwarding rule.

But I'm fairly certain that a MC server only communicates over TCP.

 

You should give the port forwarding rule a name, to better identify it later.

Remote host IP can be left empty and LoopBack should not be enabled.

 

Here is an example:

(Keep in mind that the numbers and address I've set are of course not the correct ones)

 I didn't really catch you on the server ip address, what should i put there its set automatically to 192.168.1.

The IP address of your server.
Your server has a private IP address, which you can find in the network settings of the OS.

 

For example, here you can see the network settings of my PC.

(Sorry for all the screenshots being in german, but you get the point)
Edit: I forgot to add to click properties after you clicked onto your network adapter.

 

You can also open CMD and type in "ipconfig", and there you will find the same IP address.

 

 

Again, keep in mind that you want to set a static IP address.
Your router might assign a new IP address to your server at some point, if you don't set a static IP address, which means your port forwarding rule won't work anymore.

What exactly is it that you're trying to do?

The port forwarding rule you've set seems to be correct.

Im trying to open a 2 man survival server for me and my friend, if i just start up the server and give him my ip address it wouldn't work because it needs to be portforwaded, i yesterday somehow did it right and it worked, tried it now and it doesn't work because my ip changed right? I tried to give him the new ip - doesn't work

Theres also port triggering one and dmz one, yesterday i think i got it to work by using the dmz one im not sure

Yes, you have to give him your current IP address.

This is the public IP address, so it won't start with 192.

Maybe you created a DMZ (Demilitarized Zone).

That would explain why your friend can't reach the server that is behind the DMZ.

 

Can you show me a screenshot of the settings you've enabled in the DMZ settings?

Yesterday i put there my ipv4 address

Oh I see.
This is not an actual DMZ. It's called an "exposed host" and as it says, it forwards all traffic to the host (PC) of the IP address that you put in there.

This should not be necessary and can be a security problem, but might be fine on a small scale as yours.

 

Theoretically you shouldn't do this, but if nothing else works, it might be a solution. Not that I recommend doing that tho.

 

Well, I'm not quite sure what else to recommend. Theoretically you set everything up correctly.

There could be something wrong with your subnets, but that seems rather unlikely.

 

Maybe set up a seperate rule on your server to open up port 25565 within its firewall. The firewall could block the traffic.

Another solution that might work is to create a VPN tunnel between you and your friend to bring him into your own network.
I used to do that many years ago with Hamachi. You'd have to create a session everytime he wants to join tho.

I got it to work by filling out port triggering with tcp/udp ports 25565, and dmz thing ipv4 address, also why did you say that you do not recommend doing that? is it safe
