Kill a state in States view

[Assar]

Background:
For testing issues I have placed a port forward from within LAN to destination port on external machine. In NAT I change external destination port and would like to kill established session to make this change to kick in.

States list contains this row
tcp XX.XX.XX.XX:9669 <- 192.168.3.5:9669 <- 192.168.3.158:52270 ESTABLISHED:ESTABLISHED

When I hold mouse over kill button it says
"Remove all state entries from XX.XX.XX.XX to 192.168.3.158"

When pressing button the entries disappears from current display, but sessions still exist and wont go away until application let them go.
How do I kill those sessions?
