[H-GEN] iptables assistance

[Sandra Mansell]

It has become necessary for me to add a rule to my iptables firewall
to block all packets from a particular ISP (preferably to drop them
rather than reject them). I've had a go at reading the iptables
manpage but can't seem to work out if this is possible or if I have to
just add individual IP addresses as they become a problem (I can see
the list quickly getting out of hand).... Does anyone know how to just
drop all packets from a particular domain? Or direct me to the part of
the manpage with the correct syntax (or a newbie website or something
that has what I'm looking for).

Thanks,

Sandra.
