FreeBSD '/etc/rc.firewall' shell script for configuring ipfw
Mac OS X's ipfirewall tab in the Sharing Preferences Pane
ipfirewall or ipfw is a FreeBSDIP, stateful firewall[1], packet filter and traffic accounting facility. Its ruleset logic is similar to many other packet filters except IPFilter. ipfw is authored and maintained by FreeBSD volunteer staff members. Its syntax enables use of sophisticated filtering capabilities and thus enables users to satisfy advanced requirements. It can either be used as a loadable kernel module or incorporated into the kernel; use as a loadable kernel module where possible is highly recommended[citation needed]. ipfw was the built-in firewall of Mac OS X[2][3] until Mac OS X 10.7 Lion in 2011 when it was replaced with the OpenBSD project's PF. Like FreeBSD, ipfw is open source. 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 Microsoft Windows.[4]wipfw is a Windows port of an old (2001) version of ipfw.[5]
Alternative user interfaces for ipfw[edit]
Dec 30, 2013 I want to create a Windows Firewall inbound rule to allow an inbound connection to a specific port only if the remote device is identified with a MAC Address in a subset of MAC Addresses I predefine. Effectively, loose device authentication, not network authentication (IP Address-based). Hi, First, unfortunately it's not possible to do.
- Most Mac users will be adequately protected by the built-in firewall. If you want or need extra protection, Little Snitch is an excellent starting point. If you only need to shut out one or two apps, Radio Silence will get that done most efficiently.
