redirect-gateway and p2p-Traffic

[Jan Lühr]

Hello,

http://www.tinc-vpn.org/examples/redirect-gateway/ explains how to set up a 
default route using tinc. However, in my understanding tinc's p2p traffic is 
routed via tinc there: 
Assume a network: Client A, Client B and a Server S. A and B have "ConnectTo 
S" in their config, S is used as a gateway providing 0.0.0.0/0 . All packets 
send from A to B will be delivered to <public_ip_address_of_b>:655/udp. Since 
A will route through S these packages will travel through S.

Am I right? Is there a simple workaround for enabling direct communication, if 
A and B are using dynamic ip-addresses? (Without iptables marking & policy 
based routing)

Thanks,
Keep smiling
