So pretty much whats in the title. I've done everything in terms of setting up a server normally I think, but I've always had a problem with the port forwarding part. Pretty much the port was never opened. Up until recently I've just regarded this as me being stupid or I had a weird router, but then it just occurred to me that my router is connected to a modem, but I couldn't find a guide to set up a server in this case. I don't even know if this the reason why it doesn't work.

Modem -> router -> computer
