[ale] Block Internet Access?

[cfowler at outpostsentinel.com (Christopher Fowler)]

I'm trying to keep a machine on my network off the Internet.  I've tried
this rule.

/sbin/iptables -A INPUT -p udp -i eth1 -s 192.168.1.107/32  -d 0.0.0.0/0
-j DROP

And the same for tcp.  The machine can still access the Internet.  What
am I doing wrong?
