How to fix Private Internet Access' kill switch?
When you enable the Kill Switch, PIA changes some config which apparently wasn't reverted when disabling the Kill Switch. PIA also warns you for this:



What you can do is manually revert the changes made by PIA. Running the following commands in your terminal should work:


Check the status

sudo pfctl -a com.privateinternetaccess -s rules



  No ALTQ support in kernel
  ALTQ related functions disabled
  pass in quick on ! utun2 inet from 10.0.0.0/8 to any no state
  pass in quick on ! utun2 inet from 172.16.0.0/12 to any no state
  pass in quick on ! utun2 inet from 192.168.0.0/16 to any no state
  pass in quick on lo0 all no state
  block drop in on ! utun2 inet from ! 46.166.137.225 to any

Flush/revert change by PIA

sudo pfctl -a com.privateinternetaccess -s rules



  No ALTQ support in kernel
  ALTQ related functions disabled



And also reset your DNS (Open Network Preferences &gt; Wi-Fi &gt; Advanced... &gt; DNS). It should work without restarting your Mac or anything else.
