The last two lines will not work. /etc/sysctl.conf does not understand this
syntax (only the first of the lines you listed). Put the iptables rules in a
separate script in /etc/init.d/ and create the symbolic links in the
corresponding runlevel directories using insserv. A template for the script
is /etc/init.d/skeleton.

Check the settings for the NAT table using

iptables -L -t nat

Just "iptables -L" will not show your NAT settings.

Peter
