minecraft port forwarding

[HardStroke]

ran into a problem after got my new router

new when im port forwarding it asks for an external and internal host

what do i write there?

it doesnt let me save without it and it wasnt like that with my old router

If you want to forward port 25565 for example, you would then put that in both the external and the internal port fields.

 

The reason it is like this is to provide more flexibility with port mapping, so for example if you have a server running on port 80 that you can't change to anything else, and your internet service provider blocks port 80, then you can enter another port that isn't blocked such as 3000 in the external port field, and then put 80 in the internal port field. Then you can access the service on port 3000 from outside, but still use port 80 on the inside.

i did use 25565 both internal and external but im talking about the host

my friends cant login into the server and when im adding a port it says i need to choose a host and when i put my pcs ip adress it still doesnt work

The host would be the internal IP address of the machine running the server.

If you are hosting on the same machine, you need to connect through localhost or your internal ip because your router most likely does not support NAT hairpin. Anyone outside your local network needs to use your external address to connect. If they are unable to connect then there is probably an issue with  how you have forwarded the ports

it shows that the server is not online but i did everything correctly

i port forwarded port 25565, the host is my pc, allowed java thru windows firewall but when i turn the server on it doesnt shot that its on
