Smoothwall Static routes

I eventually solved this problem.
Edit /etc/rc.d/rc.firewall.up

After the section on “# Allow packets that we know about through …”

# Allow packets from green to green
/sbin/iptables -A FORWARD -i $GREEN_DEV -o $GREEN_DEV -j ACCEPT



with this in

route add -net netmask gw dev eth0

make sure the file is 755

add this line to /etc/rc.d/rc.netaddress.up


Then reboot the smoothwall
