I think these two lines are useless (and the RH- prefix makes me think
it comes from a RedHat based system).

Anyway, here you're creating a chain you do not seem to use (unless
it is magically used by Ubuntu).

> sudo iptables -t nat -A POSTROUTING -j MASQUERADE -s 192.168.0.0/24

This one is necessary; you'd better specify the output interface with -o
(for example -o eth0).

I wonder what it's supposed to do.

> sudo sysctl -w net.ipv4.ip_forward=1

Necessary.

Don't think so :)
