I believe you would have to force ULTRAPEER mode on one of your Limewire hosts.

try putting these options in your limewire.props file on one of your Limewire hosts:


EVER_ACCEPTED_INCOMING=true
FORCE_SUPERNODE_MODE=true
EVER_SUPERNODE_CAPABLE=true

also make sure that you don't have the "Disable ultrapeer mode" option enabled or just place this option in your limewire.props file as well:

DISABLE_SUPERNODE_MODE=false
