Can't port forward for some reason
So I'm trying to port forward my rust server (video game not programming language) on port 28015 to play with some friends but I cant seem to get it working. I've exhausted pretty much all of my options like tweaking the firewall rules and changing various other settings. I'm using a tp-link archer c54 router and a comtrend ar-5220u modem and I even went as far as port forwarding on my modem too. I started to suspect that my ISP was blocking ports so I called them and they basically just told me...
