Hello,

I noticed the line:

> ech0 "1" > /proc/sys/net/ipv4/ip_forward

so if that's a typo in the email, disregard. Otherwise,
your '0' [zero] should be an 'o' to properly spell 'echo'.
You can verify if forwarding is actually happening:

	cat /proc/sys/net/ipv4/ip_forward

to see if the '1' made it in there.
