slow localhost name lookup – afp & ssh

[emerge3d]

I have an Xserve G5 running OSXS 10.5.8 and it is taking an abnormally long time (1 to 2 minutes) to connect from any client (10.4.x to 10.6.x) with either afp in the Finder or to make an SSH connection from the Terminal using the localhost name. Initial research suggests it is related to the Firewall causing slow mDNS lookups

This topic has been covered in the Apple Discussion forum…

and one solution is to run the following Terminal command:
sudo ip6fw add 01101 allow ipv6 from fe80::/10 to fe80::/10

which fixes it immediately. However after a week or so and also after a reboot (the box is only rebooted to apply security updates via Software Update) the slow connection problem rears its ugly head again. Running the above command at these times is not a viable solution.

Does anyone know of a permanent fix? Can the above command be permanently added to the Leopard Server Firewall through the Server Admin GUI?

Many thanks in advance.
Cheers, Paul
