“pfctl -s state” output explanation

Question

Can anybody tell me where can I find full explanation of "pfctl -s state" output?

all tcp 192.168.0.123:22 <- 192.168.0.234:38095 ESTABLISHED:ESTABLISHED

What direction means, which TCP infos are available like "ESTABLISHED:ESTABLISED" and so on.

Good day to you..

Answer 1

This rule means; there is a TCP (as opposed to UDP) connection from remote IP addres 192.168.0.234 port 38095 to local IP address 192.168.0.123 port 22. ESTABLISHED refers to the state of the connection.
