STUN plugin not working

I’m using the latest release of the Openfire service and the STUN plugin, but don’t seem to be able to get the STUN service to work.

stunclient.exe working.stun

Binding test: success

Local address: 192.168.1.179:54626

Mapped address: 41.144.XXX.XXX:54626

stunclient.exe using.openfire.stun

Binding test: fail

These are my settings…

stun.address.primary 41.XX.XX.XX

stun.address.secondary 41.XX.XX.XX

stun.external.addresses

stun.local.enabled true

stun.port.primary 3478

stun.port.secondary 3479

Anyone have any idea?
