Shorewall is not just a firewall (frontend), it can be used to activate 
the NAT, via the:


option in /etc/shorewall/shorewall.conf. It defaults to 'keep', but it's 
very convenient to use if you already use shorewall.

If you want to do forwarding without shorewall set it to 'keep' and do 
the setting in /etc/sysctl.conf

(for unknown reasons that never worked for me, which is why I prefer the 
shorewall way)
