#this drops all icmp packets
iptables -A input -p icmp -j DROP -f

#IP_FORWARDing
iptables -P FORWARD DROP
iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT
iptables -A FORWARD -i eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

How would i got about testing the commands?

Thanks for all the help guys and gals
