The Linksys by Cisco EtherFast Cable/DSL Router with 4-Port Switch BEFSR41 Router does not support the Windows Home Server automatic configuration over UPnP standards. You must manually configure static port forwarding on your router to point port 80, 443 and 4125 to your Windows Home Server.Manufacturer: Linksys Model: BEFSR41Firmware Version: 1.04.05Hardware Version: v4
Open your web browser and enter your router's URL. By default, this is "http://192.168.1.1". If you have configured the login information, log in with your username and password. If not, the default username and password is "admin".
Click the tab labeled "Administration" and click on Management. Make sure that UPnP is enabled. If not, enable it and click "Save Settings".
The Linksys by Cisco EtherFast Cable/DSL Router with 4-Port Switch BEFSR41 Router does not support DHCP address reservation. You must configure your Windows Home Server to use a static IP address before proceeding to the next step.
a) Click the tab labeled "Applications & Gaming" and proceed to the "UPnP Forwarding" sub-tab.
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. Some of them may already have rows and may/may not be enabled. If there aren't enough empty row, re-use a row for a protocol that you aren't going to forward. For all of these, the "IP Address" should be the IP address you gave to the Windows Home Server in step 3.
NOTES
The Linksys BEFSR41 router allows you to set the reconnection mode when using PPPoE (Point to Point Protocol over Ethernet) connection. DSL providers typically use this option. This method of connection requires you to enter a Username and Password (provided by your Internet Service Provider) to gain access to the Internet.
When using PPPoE you must ensure that the Reconnect Mode is set to: “Keep Alive: Redial Period 30 Sec.”.
All done! After you configured your Linksys BEFSR41 router for Remote Access you should test the remote connectivity from within your home and from outside of your home.
