Yes I've made sure that the IP is the same. I can't really check becuase I don't have another computer.

I live in the UK and I'm using the modem/router that they provided. The ISP is Talk-Talk

Yes the router is also a modem. After turning off the firewall the ports were closed. "openports Testing ports... Port 22126 UDP is closed. Players can not browse! Port 22003 UDP is closed. Players can not join! Port 22005 TCP is closed. Players can not download!" After enabling DMZ it still said that the ports were closed.

Hello, as you can see from the title me and my friends are not able to connect to my server. I've made sure that all of my ports are open and that i'm using the right IP address. I've ran out of ideas on how to fix this. Any help will be greatly appreciated.
