JSI Tip 8818. The 'netsh firewall set portopening protocol=[TCP|UDP] port= name= interface=” ”' command in Windows XP SP2 does NOT change the port name?

When you use the following command in Windows XP SP2 to change the TCP or UDP port name in an interface, the command returns Ok.:

netsh firewall set portopening protocol = [TCP|UDP] port = name = interface = ””

When you issue netsh firewall show portopening, you are suprised to see that the port name was NOT changed>

NOTE: If you have a single interface, netsh firewall set portopening protocol = [TCP|UDP] port = name = works.

To workaround this behavior:

1. Delete the port using:

netsh firewall delete portopening protocol = [TCP|UDP] port = interface = ””

2. Add the port back, using:

netsh firewall add portopening protocol = [TCP|UDP] port = name = interface = ””
