Do you get any error messages in your webservers logfiles? Is the
webserver the same as the gmetad server?

This sounds good. "gmetad" is basically doing the same.
On the host running the webserver, can you try to connect to gmetad.
There are two ports. The XML port (default 8651) and the "interactive"
port (default 8652) that the webfrontend uses.
$telnet gmetad-host 8651
$telnet gmetad-host 8652
quit

Hard to what is better. How big is your cluster? Multicast will likely
create more traffic than unicast. Also some switches create trouble for
multicast.
