Dear King,
Thank you for your e-mail.
You do not need to set up anything on the router in regards to
file/printer sharing on local network. Router is only getting involved
when you are accessing the Internet. For local traffic (between the two
computers) you are not using the router, you are using it just like a
hub (physical connection between the computers).
You need to modify some settings in Windows in order to enable
file/printer sharing and make computers to "see" each other on local
network.
There are many guides on the Internet which will help you to
troubleshoot Windows networking setup, here are some of them:
