opnsense Disable the pf ftp proxy handler. debug.pfftpproxy default Increase UFS read-ahead speeds to match the state of hard drives and NCQ. vfs.read_max default Set the ephemeral port range to be lower. net.inet.ip.portrange.first default Drop packets to closed TCP ports without returning a RST net.inet.tcp.blackhole default Do not send ICMP port unreachable messages for closed UDP ports net.inet.udp.blackhole default Randomize the ID field in IP packets (default is 0: sequential IP IDs) net.inet.ip.random_id default Source routing is another way for an attacker to try to reach non-routable addresses behind your box. It can also be used to probe for information about your internal networks. These functions come enabled as part of the standard FreeBSD core system. net.inet.ip.sourceroute default Source routing is another way for an attacker to try to reach non-routable addresses behind your box. It can also be used to probe for information about your internal networks. These functions come enabled as part of the standard FreeBSD core system. net.inet.ip.accept_sourceroute default Redirect attacks are the purposeful mass-issuing of ICMP type 5 packets. In a normal network, redirects to the end stations should not be required. This option enables the NIC to drop all inbound ICMP redirect packets without returning a response. net.inet.icmp.drop_redirect default This option turns off the logging of redirect packets because there is no limit and this could fill up your logs consuming your whole hard drive. net.inet.icmp.log_redirect default Drop SYN-FIN packets (breaks RFC1379, but nobody uses it anyway) net.inet.tcp.drop_synfin default Enable sending IPv4 redirects net.inet.ip.redirect default Enable sending IPv6 redirects net.inet6.ip6.redirect default Enable privacy settings for IPv6 (RFC 4941)

passed to pfil (see if_bridge(4)) net.link.bridge.pfil_onlyip default Set to 1 to additionally filter on the physical interface for locally destined packets net.link.bridge.pfil_local_phys default Set
