Port forwarding on home router
By default ALL ports on a home router are closed. Meaning no connection can be establish originating from the internet to the webserver (or any other device on the home network).
To access the webserver from the internet, ports 80 (HTTP) needs to be forwarded to the PC running the webserver.
The ports forwarding page layout and wording is different for each router brand and even model.
But in general the data to input is the same.
- Application Name: Any descriptive name (example: webserver)
- (External) Port range: (can also be a single port)
- Start: 80
- End: 80
- (Internal) Port range: (can also be a single port)
- Start: 80
- End: 80
- Protocol (Service type): both (TCP, UDP or both)
- (internal) IP address: 192.168.100.200 (the IP address of the PC-LAN accessing the webserver)
