Log Files

When troubleshooting problems with your firewall, it is very likely you have to check
|
|
the logs available on your system. In the UI of OPNsense, the log files are generally grouped
|
|
with the settings of the component they belong to. The log files can be found here:
|
|
|
|
================ ======================================================== =============================================================================
|
|
**Live View** :menuselection:`Firewall --> Log Files --> Live View` *View firewall logs in realtime, smart filtering can be applied*
|
|
**Plain View** :menuselection:`Firewall --> Log Files --> Plain View` *Just the plain contents how **pf** logs into **filter.log** *
|
|
================ ======================================================== =============================================================================
|
|
|
|
Live View
|
|
---------
|
|
|
|
Live view updates itself in realtime if a rule is matched that has logging enabled or one of the global logging options is enabled under:
|
|
:menuselection:`System --> Settings --> Logging`
|
|
|
|
For better troubleshooting you can provide a filter string. This filter may include regular expressions.
|
|
Lets assume one logging entry as one single string without special separators.
|
|
|
|
So for just displaying packets that match DNS replies from wan to your lan clients in segment 192.168.1.0/24, you have to use:
|
|
|
|
.. code-block:: sh
|
|
|
|
WAN.*:53.*192.168.1
|
|
|
|
or to be even more correct
|
|
|
|
.. code-block:: sh
|
|
|
|
WAN.*:53.*192\.168\.1\.
|
|
|
|
========== ====================== ===================== ====================== ========================
|
|
**WAN** **.*** **:53** **.*** **192\.168\.1\.**
|
|
Interface 1 or more characters first match of port 1 or more characters destination ip address
