Output

In the default text mode the program produces one record per each firewall action, for example:

TS:     2021-02-02 11:01:53.494073+0000
ACTION: BLOCK
PROTO:  UDP
SRC:
  SCOPE:   global
  IF:      n/a
  IP:      213.230.86.36
  PORT:    29960
  HOST:    36.64.uzpak.uz
  NET:     213.230.86.0/24
  NAME:    UZTELECOM-DYNAMIC-CUSTOMERS-CGN
  DESCR:   n/a
  COUNTRY: UZ
DEST:
  SCOPE:   private
  IF:      wlp2s0
  IP:      192.168.0.6
  PORT:    53233
  HOST:    m-desktop
  NET:     192.168.0.0/24
  NAME:    n/a
  DESCR:   n/a
  COUNTRY: n/a

In JSON mode the output is a JSON array of records each equivalent to the above, for example (pretty-printed for readability):

{
  "SRC": {
    "IP": "213.230.86.36",
    "SCOPE": [
      "global"
    ],

  },
  "DST": {
