+% DLT_GATEWAY.CONF(5)
+
+# NAME
+
+**dlt_gateway.conf** - DLT configuration file for gateway
+
+# DESCRIPTION
+
+The configuration file dlt_gateway.conf allows to configure the different runtime behaviour of gateway in Multinode feature.
+
+The configuration file is written in an INI file format and contains information about different connected passive nodes.
+
+If Multinode feature is enabled, dlt-daemon loads by default the configuration file /etc/dlt_gateway.conf.
+
+An alternative configuration file can be loaded by changing `GatewayConfigFile` in dlt.conf(5).
+
+# GENERAL SECTION
+
+### Interval
+
+Time interval for reconnection to passive Node in second.
+
+    Default: 1
+
+# PASSIVENODE SECTION
+
+Each passive node’s connection parameters are specified in a unique numbered separate section
+
+([PassiveNode{1,2, …N}]).
+
+    Example: [PassiveNode1]
+
+### IPaddress
+
+Because TCP is the only supported communication channel,
+
+the IPaddress and Port of the Passive DLT Daemon has to be specified.
+
+IP Address of passive node. Mandatory
+
+### Port
+
+TCP port. Default 3490 is used if no port is specified.
+
+    Default: 3490
+
+### EcuID
+
+ECU identifier of passive node. Mandatory.

+    OnStartup   The Gateway DLT Daemon tries to connect to the Passive DLT Daemon
+                immediately after the Gateway DLT Daemon is started.
+    OnDemand    The Gateway DLT Daemon tries to connect to the Passive DLT Daemon
+                when it receives a connection request.
+
+### Timeout
+
+Stop connecting to passive node, if not successful after 10 retries.
+
+After <Timeout> of retries, the connection to passive Node is marked as DISABLED.
+
+It means there is no any retry anymore.

+    DLT_SERVICE_ID_GET_DEFAULT_LOG_LEVEL           0x04
+    DLT_SERVICE_ID_GET_SOFTWARE_VERSION            0x13
