question about port forwarding

[AlexStarr]

so i am trying to run a local minecraft server for me and my frieds and from what i am seeing it requires something called port forward so far i have gotten every thing right but i came across a problem when port forwarding and triggering happens when i was making the port trigger the router said it need to have a different external port because of conflict  with another but from all the guides ive been looking at they had no problem with any chance for a solution my router is a tp link archer 64

What port are you trying to open?

I am abit confused on this question so the thing is that there is this setting in the local minecraft server that requires port forwarding apparently to allow fried from different location to play and thats the server port and whil doing this i saw a guide that had both the port forwarding and port trigger in the same section but my rounter keeps it seperate and for it i set what the port (25565) need to be set on the port forwarding page but when i waa trying to add the port trigger the external port has a conflict with the other and so i cannot set it as that

Which port to which port are you trying to forward? Is there a modem/router of your ISP between the internet and your TP link?

You need an internet facing port and an internal port and IP, so your router can route traffic from an outside port to the inside port.

You want to use port 25565, so you use 25565 on the outside to internal IP 192.168.0.5 (for example) and port 25565, so someone from the internet connecting to your public IP with port 25565 will be forwarded to the host with IP 192.168.0.5 and port 25565.

 

Maybe post a screenshot of the port forwarding page of your router?

In order to have port forwarding you need a few things. Firstly you need the IP address of your server to either be static OR reserved in the DHCP server, as you dont want the IP address to change. You will input that address in to your port forwarding rules like in the picture. Second you need the port you want to forward. As you notice in mine I have port 7777 forwarded (I dont recall what this is for). Third you need the protocol TCP, UDP, or both. Remember these port forwarding rules also need to happen on the device as well as most OS's now days have their own built in firewalls. 

 

The most important thing. The router needs to have a public IP address assigned to it by the ISP. I mention this because if your router is behind another router, it wont have a public IP address assigned. Most ISP's give you a modem router combo, most people just connect a router to those not knowing any better. OR worse yet, your ISP has ran out of public IP's so it's doing carrier grade NAT. NAT is the solution that we use to share the 1 IPv4 address the ISP gives you with all your machines. ISP's started using this standard on their networks as we started running out of IPv4 addresses. 

 

Here are the private IP address ranges.

 

• 10.0. 0.0 to 10.255. 255.255.
• 172.16. 0.0 to 172.31. 255.255.
• 192.168. 0.0 to 192.168. 255.255

If the WAN IP address of your router falls with in this range that means your double NATed and port forwarding wont work, at least not easily. Now like I said, if you have an ISP supplied modem/router combo then you have options for get around double NAT. However, if your ISP does not supply a public IP, then it becomes a lot more of a hassle.

Is it fine to post a screenshot since there is my ip address on it?

dont forget windows has a firewall aswell!
