Hi,
I would like to know how to completely lock down the firewall allowing only the explicitly specified rules in the packet filter. By default, during the installation, the wizard creates some default firewall rules for Internal to External zone. However I don't see any blocking rule for External>Internal traffic. I created a blocking rule as "Any" (Source) "Any" (Service) Internal Networks (Destination) and placed it in the bottom of the rule.I wonder whether above rule would be sufficient enough to block all the incoming traffic except the explicit rule specified allow rules placed above the blocking rules.
I appreciate your help!
Regards
Sankar
