 # Notes:
 # - This file uses the WinDivert filter language, see:
 #   (https://reqrypt.org/windivert-doc.html) for more information.
-# - This is filter in addition to "web-only" mode; the two filters operate
-#   independently.
-# - ipv6 and non-tcp (except port 53 UDP) will be dropped regardless of what
-#   this file specifies.  However, it is more efficient to filter such
-#   traffic here.
-# - Traffic is dropped if and only if the filter evaluates to "true".
