Quite honestly I think you are better off using N2N as it doesnt require you to login into some account manager to create a network
see http://www.ntop.org/products/n2n/
its honestly as simple as
#supernode > supernode -l xyw
#edge node1> edge -a 10.1.2.1 -c mynetwork -k encryptme -l a.b.c.d:xyw #edge node2> edge -a 10.1.2.2 -c mynetwork -k encryptme -l a.b.c.d:xyw
now if you provided me a central way that i could manage the system, and didnt force me to use your "portal" id be much happier.
the zerotier client was a simple command.....
If you want to test by joining the Earth network, try:
sudo ./zerotier-cli join 8056c2e21c000001
though I refuse to use infrastructure outside of my control. let us create our own portal, and it might be more likely to be used.
