Hi, It was hard to co-exist an IPv4 firewall rule and an IPv6 firewall rule in the past. By revision 206382, The rc.firewall and rc.firewall6 were unified, and rc.firewall6 and rc.d/ip6fw were removed. According to the removal of rc.d/ip6fw, ipv6_firewall_* rc variables are obsoleted. Instead, the following new rc variables are added to rc.d/ipfw: firewall_client_net_ipv6, firewall_simple_iif_ipv6, firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, firewall_simple_onet_ipv6, firewall_trusted_ipv6 The meanings correspond to the relevant IPv4 variables.
