SYMPTOMS
If your Microsoft Windows XP-based computer is running Routing Information Protocol (RIP) Listener, RIP Listener may not update the route table with new route information.



CAUSE
This issue may occur if a firewall is preventing RIP Listener from receiving route information that is sent by routers that are using RIP version 1. When you install Windows XP Service Pack 2 (SP2), Windows Firewall is turned on. If your computer has Windows Firewall or another firewall turned on, incoming UDP port 520 may be blocked.



WORKAROUND
 Click Start, and then click Run. In the Open box, type wscui.cpl . Click OK. Click Windows Firewall. Click the General tab, and then click to clear the Don't allow exceptions check box. On the Exceptions tab, click Add Port.</li> In the Port number box, type 520 .</li> Click UDP.</li> In the Name box, type the following text:

520 port opening for RIP Listener

</li> Click OK.</li> Select the 520 port opening for RIP Listener check box, and then click OK two times.</li></ol>
