I bought my own router to address the fact that i wasn't able to play Forza 7 multiplayer. However a month after i purchased the router the multiplayer has stopped being accessible. I have also in the meantime started a private Minecraft server for my friends and I. I had properly opened the ports to make that work but now the ports are closed and no one can access the server. Could the issue be on Shaws end? Because it was working and then one day is just wasn't
Which Shaw cable-modem do you have? Is it in "bridged" mode? Or, "IP Passthrough" mode? Are you port-forwarding on that device?
Which router do you have? Are you also port-forwarding on that device to your private server?
If you connect your private server directly to the Shaw device, is it accessible from the Internet?
