Hi @dd1982

@Anonymous has asked me to help you with this. Please can you confirm which make/model of router you are using? In your reply, please include a screenshot of the port forwarding rule that you have configured, so that I can check it for you.

There is nothing wrong with your rules. I used the same & they are both open:-

TCP 443TCP 25565

When you say that you can't access the servers from your WAN interface, how are you testing this? If it is from another device locally connected to your router & targeting the server via the router's WAN IP address or DDNS domain, then you won't be successful. This is because of NAT loopback, which all TalkTalk routers consider a security vulnerability. Whenever a local device tries to go out to the internet & back into the router again, it is blocked by the router. If you have a smartphone, disconnect it from the WiFi & test using mobile data.

Yep that was it. I've never had any router that does that before. Thank you
