macOS Sierra 上的 PF 阻止了一些本地网络流量，从而允许其他

我的 Mac Mini 2012 上运行着 pf，系统为 OSX 10.12.2。除了一些奇怪的情况。我可以与无线网络打印机通信，但无法通过以太网与 HP 2015 通信。互联网很好。似乎只是本地网络。

如果我通过其 Internet 接口地址和端口转发访问它，我可以通过 Microsoft 远程桌面与办公室的另一台 Windows 笔记本电脑通话。但是……我无法通过本地以太网与它通话。我显然在 pf 规则集中遗漏了某些内容，但是什么呢？

我知道这是 PF，因为如果我禁用 pfsudo pfctl-d，突然我又可以和他们所有人交谈了。或者这两个服务都是 UDP？

这是 pf.conf 规则集 # # com.apple 锚点 # set skip on lo0

#not sure about these two
tcp_services = "{ ssh, smtp, domain, www, pop3, auth, pop3s }"
udp_services = "{ domain }"

答案1

我找到了答案。我想我补充了

pass in  on en0 from 192.168.0.0/24 to 192.168.0.1
pass out on en0 from 192.168.0.1    to 192.168.0.0/24
pass in  on en1 from 192.168.0.0/24 to 192.168.0.1
pass out on en1 from 192.168.0.1    to 192.168.0.0/24
# pass all traffic to and from the local network.
# these rules will create state entries due to the default
# "keep state" option which will automatically be applied.
pass in  on $int_if from $lan_net
pass out on $int_if to   $lan_net

答案2

我的最终 pf.conf 文件如下。有几个注释选项我会回头再看。第一个是 antispoof，如果设置了，会阻止我连接到路由器 Web 界面吗？最后一个是 int_if 集，我只需要定义它们。总有一天。

# This file contains the main ruleset, which gets automatically loaded
# at startup.  PF will not be automatically enabled, however.  Instead,
# each component which utilizes PF is responsible for enabling and disabling
# PF via -E and -X as documented in pfctl(8).  That will ensure that PF
# is disabled only when the last enable reference is released.
#
# Care must be taken to ensure that the main ruleset does not get flushed,
# as the nested anchors rely on the anchor point defined here. In addition,
# to the anchors loaded by this file, some system services would dynamically
# insert anchors into the main ruleset. These anchors will be added only when
# the system service is used and would removed on termination of the service.
#
# See pf.conf(5) for syntax.
