Hi,

You can read about states at http://en.wikipedia.org/wiki/Stateful_firewall for example. And concurrent connections for ipv4 can be viewed using netstat command:

netstat -anfinet

and ipv6:

netstat -anfinet6


You can check for currently established connections with the command like this:

netstat -anfinet | grep ESTABLISHED

concurrent connection?
