Hi all,

 

I've set up Port Forwarding on my router, but it seems, that it doesn' work. I've forwarded the port 25565 like this: (NAT Forwarding -> Virtual Servers)

 

25565 is the port for Minecraft servers. There's a server running on 192.168.1.109 and i can connect to it internally (In my local network), but not from the internet.

It's also not possible to ping the router from the internet. (https://whatismyipaddress.com/de/meine-ip to get my ip and ping with a Windows PC like "ping 12.345.678.910")

I tried to ping that IP from my own network and from another network, because a long time ago I had problems pinging my own internet ip address from the local network.

 

I thought, that this could be a firewall problem caused by the router, because some devices just don't allow ICMP, but I got the same result after disabling the firewall like this:

 

 

I hope you can help me with that issue.

 

BTW: Forwarding Port 22 (SFTP) isn't working, too.

Three Uk SIM?

 

You probably are not getting a genuine real public IP address.

 

This can be resolved.

@NooNoo 

Exactly. I was not getting a public IPv4 Address from my provider. I was in a carrier-grad-nat. 

 

I live in Austria, where you have to get a public address if you request it. So I requested it, got it and everything is working fine. Router settings were OK all the time. 

 

Thank you for your reminder, to post this!

Some providers use a different APN to allow a public IP to be assigned (if available). With Three UK it's a simple APN change ;)

Hi, You might need to require a public IP from SIM card carrier.

Some providers use a different APN to allow a public IP to be assigned.

Thanks a lot.

@hauberl Sag deinem Provider du willst eine öffentliche IP. In Österreich sind sie gesetzlich dazu verpflichtet, dir eine zu geben, wenn dus willst. Zumindest meines Wissens. Bei mir hats direkt geklappt, ich bin bei Educom.
