Make sure you read the 127.0.0.1 example for the "allow"... it has to be 
a regex... not just an IP address.

^123\.123\.123\.123 - example.
123.123.123.123 - won't work.

Telnet from the main machine to port 4949 of the remote machine.  Make 
sure you get a prompt back that says you're connected to munin.

(It gives you a prompt and then hangs... the usual CTRL-] to bail out to 
the telnet "shell" and a "quit" will drop the session, of course... 
standard telnet stuff...)

tcpdump helped me figure out that I was firewalling off port 4949 on one 
box also...
