FreeBSD: Block Brute-force Attacks Using Sshguard and IPFW
Mac Security: Firewalls | Macworld In security parlance, ipfw is a packet-filtering firewall: it checks each packet coming or going through the Mac’s network interfaces against a set of rules, and allows it to pass or blocks it. The FreeBSD Diary -- Firewalls, filtering, ipfw, and FTP ipfw allows you to control the IP coming in and out of your machine. Basically, it's a tool which can be used to set up a firewall between your subnet and the rest of the world. You can block certain things, allow others, or allows protocols only from known addresses. SSHGuard SSHGuard can integrate with many firewall backends including: FirewallD (Linux, new in 2.0) ipfw (FreeBSD, macOS) IPFILTER (FreeBSD, NetBSD, Solaris) netfilter/iptables (Linux) netfilter/ipset (Linux, new in 2.0) PF (OpenBSD, FreeBSD, NetBSD, DragonFly BSD) tcpd's hosts.allow (boxes without a network-layer firewall) IBM AIX's firewall

29.6. IPFW - FreeBSD IPFW is a stateful firewall written for FreeBSD which also provides a traffic shaper, packet scheduler, and in-kernel NAT.. FreeBSD provides a sample ruleset in /etc/rc.firewall.The sample ruleset define several firewall types for common scenarios to assist novice users in generating an appropriate ruleset. firewall - FreeBSD ipfw firewall_type - Server Fault Line 1: bad command `${fwcmd}' Firewall rules loaded. /etc/rc.d/ipfw: DEBUG: checkyesno: firewall_logging is set to YES.

It is used in many FreeBSD-based firewall products, including m0n0wall and FreeNAS. A port of ipfw and the dummynet traffic shaper is available for linux, openwrt and Windows. wipfw is a Windows port of an old (2001) version of ipfw. Procedure. Modify the ipfirewall ruleset and/or its supporting definition files.
