Section 31.9.3 suggests net.inet.ip.fw.default_to_accept="1" "during the first attempts to setup a firewall and NAT gateway". Section 31.9.5 suggests I "specify a predefined firewall ruleset that allows anything in" with firewall_type="OPEN" Question: What is the difference between these two configurations (or where can I go to learn the difference between the two)? Thank you, Chris
