When I turn ipfw2 off, this effect is gone. It was never happened for old ipfw with the same settings. I have simple "open" firewall type with one "deny" rule for specific tcp port. Since this is remote machine, I can't login and see what actually happens during this effect. I also notice that if current connection stays across beginning of effect, it continue to work, but new ones hangs. -- Andrey A.
