Suppose two NAT routers has enabled 6to4.

When one client from each side behind the NAT firewall connect to the public ip of the other side, will the 6to4 connection between the two routers break or will the protocol 41 tunnel between the clients break? As I find that only one client is allowed per public ip pair under the NAT firewall.
