Keep connectivity in Tinc VPN alive!

[philip shangguan]

I have a simple 3 hosts virtual network setup with tinc vpn. Three hosts
are using ips as A-10.0.0.1, B-10.0.0.2, and C-10.0.0.3.

All 3 hosts(A,B,C) are in three different networks. B and C uses
"ConnectTo" in their tinc.conf to connect to A's external IP. After all the
setups are done, such as key exchanges etc, and start the tinc daemon on
all hosts, the connections among the 3 hosts are working with their ips
defined above.

My question is that, once the initial connections are established, can B
and C talk to each other directly without going through A? What if A is
down, can B and C continue talking to each other? With the simple setup I
have now, it does not work if I shut down A. Is it possible with some
configure changes, I can have A to instruct B and C to communicate directly
with each other? I am trying to get B and C to work as a pair of P2P hosts.

Thanks,

Philip
