VPN Client fails to function with Windows XP after an upgrade to Service Pack 2


If you use a Cisco VPN Client version earlier than 4.6,  add a rule in the Microsoft firewall to allow User Datagram Protocol (UDP) port 62515. To do this, perform one of these procedures:

  • Microsoft Firewall GUI.
  • Add an exception rule.
  • Enter this command from a DOS prompt:

netsh fi add port UDP 62515 "Cisco VPN Service" enable all

As an alternative, upgrade the VPN Client to version 4.6 or later.
