If HostComputer has iptables installed, you need to run these commands (replace eth0 with the interface HostComputer uses to connect to the internet):
/bin/echo "1" > /proc/sys/net/ipv4/ip_forward
/sbin/iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
You also need to let www traffic through:
/sbin/iptables -A FORWARD -p tcp --dport 80 -j ACCEPT
/sbin/iptables -A FORWARD -p tcp --dport 443 -j ACCEPT

ClientComputer only needs to have HostComputer as the default gateway.

See the ipmasquerading howto for more info.

You should also create some stronger firewall rules once you get it running
