b) You need to enable forwarding for 3 different ports: HTTP (80) , HTTPS (443) , RWW (4125). Each of these will need its own row on the table. For all of these, the "IP Address" should be the static IP address you gave to the Windows Home Server in step 3.

When using PPPoE you must ensure that the Reconnect Mode is set to: “Always On”.
All done! After you configured your Linksys by Cisco Wireless-G Broadband Router WRT54G2 for Remote Access you should test the remote connectivity from within your home and from outside of your home.
