This one is for the archives.
If anyone would donate their time to replying to this one, It would be =
appreciated.=20

Im trying to setup a firewall that for a time-limited period block IP's =
that send packets to specified ports.
After time has expired the ip will be allowed again.

With this setup;

	ipfw add 100 check-state
	ipfw add 1000 skipto 2000 tcp from any to any 445
	...
	ipfw add 2000 deny ip from any to any keep-state
	...

Would this setup a stateful block against that IP address, blocking all =
IP traffic from that particularly evil ip
Or would it just match the specifics? Would I have to do this instead to =
achieve this?

	ipfw add 100 check-state
	ipfw add 1000 skipto 2000 tcp from any to any 445 keep-state
	...
	ipfw add 2000 deny ip from any to any
	...
