cannot use port 25566?

i want to have bukkit use a port thats not 25565, for exaple port 25566. but when i change the properties to 25566 i cannot connect to it.

yes my ports are open and no i do not have a firewall.

heres my server config:

#Minecraft server properties
#Thu May 16 16:10:26 EDT 2013
generator-settings=
allow-nether=true
level-name=Baconia
enable-query=true
allow-flight=false
server-port=25566

Locked. Offline mode is not supportable.
