Your routing seems to be set correctly. Make sure you are pinging sites
which do not block ICMP - eg. google.com. Also, When you enable NAT on the
Server, you automatically enable the Basic Firewall. If you are also
running firewalls on the client machines, try disabling them. Sometimes if
you also run a firewall on a client PC behind a NAT firewall, you may
experience this problem.
