Perforce: Connection timed out.

I’ve been working on trying to set up a perforce server so my friend and I can work on a project together. I’ve followed just about every video and blog I’ve been able to find on the topic, but nothing seems to work. I’ve set up port forwarding on my router and made sure my Anti Virus will allow perforce to go through. When I use some kind of port checker, I get “Connection Timed Out”. I follow the most common Perforce server set-up videos. I’m not sure what I could be doing wrong. I was wondering if anyone has knowledge on this topic? Thank you.
