Hi all,

I've been trying to get a ruleset for IPFW but was unable to figure out
how to do it :(
I'd appreciate it if someone can reply with the right ruleset for the
following:

1) allow traffic from 0.0.0.0 - XXX.128.0.0 
2) block traffic from XXX.128.0.0 - XXX.146.159.255
3) allow traffic from XXX.146.160.0 - 255.255.255.255

Thanks in advance.

/Taz

P.S.: IP's are imaginary of course.
