Linksys EtherFast Cable/DSL Routers

(For product details visit

Linksys EtherFast Cable/DSL Routers provide NAT (Network Address Translation) and port mapping.

Computers and devices behind the router all have 192.168.1.X IP addresses, which are translated into a single public IP address by the router.

To run a server behind the router, incoming TCP/IP traffic must be "mapped" to the server on a private IP address (192.168.1.X) based on port numbers.

linksy1 Log into the router (open in your browser), Username is blank and the password is admin if you have not already changed this.









Select the "Forwarding" tab. In an available line, enter the service port you wish to open and the IP address of the computer which will handle the requests


NOTE: If you are running servers (any type) behind a NAT router, the DNS records for these servers must point to the public Internet IP address - not the private server IP address (192.168.X.X).
