im running linksys router WRT54G version 2 flashed with DD-WRT. ive added
the following command:

iptables -I FORWARD -d 74.138.*.* -j DROP

and wonder if its valid? my objective is to block access to a user coming
in from various IPs starting with 74.138. i realize that if this works it
will block everyone from that IP scope but i do plan to remove it after a
few weeks when he has lost interest.
thanks,

You need to specify source address, not destination address, and use
a netmask, not wildcards. Try this:

iptables -I FORWARD -s 74.138.0.0/16 -j DROP

As usual: I recommend to contact the ISP, and email a log. That way it
will stop, and others are helped as well.
