I am working on my site-wide gateway and am considering turning off the ip_forwarding networking parameter. This will require me to configure the nddconf file. As well as turning the parameter off, I want to specify which interfaces I want to keep the parameter active for; in other words, I want to allow a number of secure networks to communicate through the site-wide gateway. To achieve this, I will need to include the IP_FORWARDING_INTERFACES="<interface> <interface> " parameter in the nddconf file. True or False?
