    I have found an interesting problem with the WRVS4400N firewall rules. I suspect that some other routers share this problem.

    If a firewall rule is set-up to block any traffic to or from a port at a certain time it will do so for new connections. Hiowever it will NOT close existing connections.

    For example: if I block World of Warcraft port 3724 during work hours it will stop anyone from opening WOW during these hours. It will not, however, stop anyone who happened to be active and playing when work hours commenced. They will still be able to continue until they stop the game. They will then be unable to start again until after work hours and the BLOCK rule ceases.

    Can anyone comment?
