安装配置完成FreeBSD之后，我们需要配置一个防火墙来保护我们的服务器。 在这里，隆重向大家推荐我们的PF防火墙。 PF防火墙是OpenBSD的一个项目，在此，向OpenBSD开发团队表示感谢，虽然从来没有用过OpenBSD，但是OpenSSH天天用，现在PF也在用了。

Oct 02, 2008 · Q. Under FreeBSD 7.0 patch level 5, I'm getting following warning message: Enabling pf. No ALTQ support in kernel ALTQ related functions disabled No ALTQ support in kernel I need ALTQ support for my FreeBSD box. How do I enable ALTQ for Class Based Queuing (CBQ) to divide a connection's bandwidth into different classes or queues to prioritize traffic based on filter rules? VM1 has the pf.c that comes with the FreeBSD-CURRENT source, whereas VM2 has a patched version of the file, which performs a sanity check on the requested memory by malloc(9) against the RAM size. If the requested memory is more than the available memory, ph_hashsize is set to PF_HASHSIZ, which 32768. pf-badhost + unbound adblock v4 adds support for FreeBSD! Hey folks, just thought I'd share with you that I've released the latest versions of pf-badhost and unbound-adblock which add support for FreeBSD :) ;) If /dev/pf isn't being created despite pf being built-in, it could indicate some strange bug in the pf module (where it prefers to be loaded as a kernel module), OR, a problem with devfs (the filesystem that controls /dev on FreeBSD) on your machine.

2012-2-25 · FreeBSD下的PF FreeBSD下的包过滤工具有IPFW，IPF以及PF，它们各有特点。PF原本是OpenBSD下的包过滤工具，FreeBSD开发人员已经把PF移植到了FreeBSD上了。如果要在FreeBSD上使用PF，需如下操作： 1. 编译内核： cd /usr/src/sys/i386

2011-12-6 · 30.4.2 PF 内核选项 虽然你不必亲自把对 PF 的支持编译进 FreeBSD 内核，但是有时你仍然需要这么做来使用到 PF 的某些没有被收录进可加载模块的高级特性，比如 pfsync (4) 伪设备用来发送某些改变到PF 状态表。 它能配合 carp (4) 使用 PF 建立支持故障转移的防火墙。

Jan 21, 2017 · PF, the OpenBSD firewall, is included in the FreeBSD base install. People argue about performance between PF and IPFW, but I think PF's syntax is the easiest of any firewall in existence. We'll use a simple PF setup—just blocking all inbound connections except to specific services we allow. The PF configuration lives at /etc/pf.conf:

В июле 2003 программный межсетевой экран OpenBSD, известный как PF, был портирован в FreeBSD и стал доступен из коллекции портов FreeBSD; первым релизом, где PF был интегрирован в основную систему, стала FreeBSD 5.3 в ноябре 2004.
