Source Server Not Showing on Master Server

[Penduk]

Hello helper(s),
I downloaded a server downloader which gave me all the normal stuff (definitely not the problem as I had it working and downloaded on another computer at a friends) and made it a new frontline map cp_frontline_a1. I ran the server with the start.bat (code below #1) and it has lan_server 0 (making it an internet server) unfortunately I can access it from any computer at home by going to lan but when I check on my other computers at home it does not show my server.

EDIT: Turns out my ports aren't open and apparently haven't port forwarded 27000-27050
