How to open port 80

[Poopstinks]

Hello, I need to open port 80 on my computer. I turned off my router's firewall for testing reasons and port 80 opened but i dont want to keep the firewall down. My router is an XMR100. Any ideas how I can make an exception for port 80?

Put a ststic IP on your PC, then port forward port 80 to the PC's IP address. I'm not familiar with a XMR100, so read the manual on port forwarding.
