Parameter Description
Dead Peer Detection
maximum fail
A number of DPD messages that were sent to check the status of a
remote host and left unanswered. By default, the value 3 is specified.
If a remote host does not answer the specified number of messages,
the router breaks down the tunnel connection, removes the encryption
keys, and tries to activate the connection.

the size of a TCP packet which will be sent from a remote host to the

If the Manual value is selected, you can specify the parameter in the
TCP MSS Value field.
If the Path MTU Discovery value is selected, the parameter will be
configured automatically.
