Of course, NAT is still missing, so let's add another line here:

  iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
  echo 1 > /proc/sys/net/ipv4/conf/eth0/forwarding
  echo 1 > /proc/sys/net/ipv4/conf/eth0/proxy_arp 

Of course, it would be neat to do NAT only for packets coming from
eth0. But I fear that's not that easily done without resorting to -j
MARK and suchlike.
