The method to configure network ports for a firewall differs depending on the manufacturer of the software firewall or the manufacturer of the router. See the manufacturer’s documentation or contact the manufacturer for more information about opening specific ports to allow network traffic.
If you have leased your router from your ISP, contact your ISP for more information.
If you live in a dormitory on a college campus that provides your Internet service, contact the school IT department and give them the TCP/UDP port information that is listed earlier in this article.
If you live in a pre-wired apartment complex and connect through an Ethernet port without any other external devices, contact the apartment complex and give them the TCP/UDP port information listed earlier in this article.
