Najprej dovoli dostop samo IPju 10.5.5.2 do subneta 192.168.1.0/0, potem pa
z rulom zablokiraj dostop celotnemu subnetu 10.5.5.0/24.

Jaz npr. blokiram določenim mašinam dostop do neta na takle način:
/usr/sbin/iptables -t nat -A POSTROUTING -o $EXTIF -s 192.168.1.50 -j DROP
/usr/sbin/iptables -t nat -A OUTPUT -o $EXTIF -s 192.168.1.50 -j DROP

Kako preprečim subnetu 10.5.5.0/24 dostop do 192.168.1.0/24, vendar pa
pustim dvema mašinama do ftp na 10.5.5.2. Te dve mašini sta 192.168.1.31 in
192.168.1.37.

Hvala!
