How to add port mapping in router?

We take Linksys for example. Please visit http://192.168.1.1 and input router username and password(default username is 'admin' and password is 'admin').

1. "Application & Gaming" -> "Port Range Forwarding".
2. Application: ccfile; Start: 80; End: 80; Protocol: Both; IP Address: 192.168.1.101; Enable.
3. "Save Settings".
Notes: Start and End is corresponding to the CCFile's port in 'Options'. IP Address is corresponding to the PC's LAN IP address which installed CCFile.
