Date: 2012sep23 Update: 2026oct17 Keywords: server behind NAT Q. NAT: How to make a server that's NATed available on the Internet (NAT = Network Address Translation) A. Suggestions: 1. Change the settings on your router to forward to the port. 2. If your IP-address can change, use a server to iron that out. 3. Use Tailscale. More info: 1. To forward a port you need to know how to login to your router as administrator and the port number of your server. On a Linksys WRT router this is under "Applications and Gaming". http://portforward.com/ 2. If your ISP gives an IP-address that changes - dynamic IP-address - you can use http://dyndns.org or http://no-ip.com or other services to sort this out. Access your computer by domain name - not IP-address. 3. Tailscale https://tailscale.com is great. But its overkill for simple cases.
