I need to setup an iptables script for an untrusted lan network , the firewall should only connect to two or three ip address on the lan and drop any other ip address on the lan .

I think this would do it:

iptables -t filter --append INPUT --destination <ip address 1>,<ip address 2>,<ip address 3> -j ACCEPT
iptables -t filter --append INPUT -j DROP

so if the packet is going to one of the three trusted computers it gets accepted, otherwise dropped.
