It could be good to add third possibility in router configuration for NAT and Firewall. Now we have 2 choices enable both or disable both. I have managed this manually editing rc_masq file and rc_user file. In each new FREESCO version rc_masq file becomes more complex and with more variables. As I am not programmer, upgrade to any new version takes lot of time to manage Firewall ON and NAT OFF.
Thank you in advance.
