Can anyone tell me whether or not new or updated rules made to ubuntu (v10.10) UFW should affect existing connections? I have noticed that these only take effect the next time I try to reconnect, which doesn't seem to me the way a firewall should behave!
What I'm trying to achieve here is to simulate a connection being lost/dropped in a socket based client.
Is there any way to update these rules immediately so as they affect existing connection?
