Behind a NAT - snoj/node-gossip GitHub Wiki
While the comment in /lib/gossiper.js would like me to think otherwise, it is possile to hack things to get this to work behind a NAT. (Works as of commit)
var gossip = require('./node-gossip').Gossiper;
var seed = new gossip(9000, [], '192.168.1.10');
seed.address = '54.0.1.2';
seed.start();
