 If you enable firewall logging, you should consider selecting **Show rejected packets** as that setting will log all packets stopped by the firewall, but not every single packet passing through.

   * **Log SIP methods** - Filter logging of SIP messages by method. If the word "not" is prepended all SIP messages that not matches the methods listed will be logged. Examples: "not REGISTER" or "INVITE ACK BYE CANCEL".
   * **Log only communication with IP addresses** - Filter the logging of SIP messages. Only SIP messages sent or received to the given IP addresses are recorded into the SIP Log.
+  * **Log internal SIP messages** - SIP messages may be sent to/from internal applications of the box, when this checkbox is checked all messages will be logged. Otherwise only message sent out or received from the network will be shown.
+This section contains also settings for the logging for telephone ports and built-in IVR units (auto attendant, conference unit, voicemail unit, testagent unit):
+  * **Log telephone port and IVR unit calls** - Use this checkbox to get a logging for each start and end of a call where a telephone port (FXS/FXO) or an IVR unit is an endpoint.
+  * **Telephone ports and IVR units debug messages** - Use this checkbox to get a lot of debug output for each call where a telephone port (FXS/FXO) or an IVR unit is an endpoint. Should only be enabled for debug purposes, because it needs quite a lot of processing power.
 The SIP log can be viewed on the [[SIP log page]] or forwarded to various receivers, see below.

 Log entries in all logs can be logged to files on an attached USB memory. Logging starts automatically when an inserted USB memory has a **/log** folder on it. Log files are created for each log (system/firewall/SIP etc) and filled with log entries as they occur. New log files are created for each power on.
-:?: If logging does not start then check that the folder is named **/log** (not /Log !), the file system of the USB memory is FAT32, and **Read only access* is disabled on [[USB Web server page]].

+==== Forward to syslog server ====
+Log entries in all logs can be forwarded to remote [[wp>syslog]] servers.
+Contents of the **system** and **firewall logs** can be sent to the **primary syslog server**.
+Contents of the other logs can be sent to that primary syslog server too, or to other dedicated syslog servers.
+:!: **WARNING!** Logging all packets in the firewall log, and enabling forwarding of firewall log to a syslog server generates **one extra packet** of data traffic for **each and every packet** received or sent by this unit! This not only reduces performance/bandwidth of this unit but your entire network! Use with extreme care!
+Do not forward ACCEPT log entries - To reduce network traffic you can set "Firewall Log" above to "Show all packets", enable "Forward firewall log to primary syslog server" and enable this setting. Then all sent/received packets will be logged in the unit's internal firewall log, but only ERROR/DROP/DENY entries will be forwarded to the syslog server.
+==== Send as e-mail ====
+Log entries in all logs can be mailed to an e-mail account. To be able to send e-mails you must supply address of an SMTP server on the [[E-mail page]].
+For performance reasons log entries are //not// mailed one-by-one, but as log files containing several log entries. Thus reporting through e-mail can be delayed until more log entries are collected.
+The generated e-mail contains the severity level of the most severe event logged in the attached log file. Please notice that the message always lists only ONE log entry - there might be more log lines in the attached log file with similiar severety!
+You can limit the amount of logs e-mailed by selecting what severity level of an event must have been occurred for an e-mail to be generated. (As the firewall log has no severity levels it cannot do such filtering.)
+==== Forward to SNMP server ====
+Log entries in all logs can be forwarded, embedded in [[wp>SNMP#Trap|SNMP traps]], to a remote [[:settings and administration:SNMP]] server.
+By specifying a community and IP address SNMP traps can be generated for log events with selected severity levels or higher.
+Log traps sent have OID .1.3.6.1.4.1.1218.1.5.0.0
+Installing Internet Gate's customer specific MIB makes receiving log traps easier. [[:settings and administration:SNMP|Read more here]]
