The line

iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE

should be using interface eth1 not ppp0 as you (probably) don't have a ppp 
interface.

Also you should add this

echo 1 > /proc/sys/net/ipv4/ip_forward

to enable IP forwarding. The redirect line isn't needed to do MASQ, the 
above 2 lines alone should do it.
