keepAliveTimeOut
Use this element to set the amount of time (in sec-
onds) the tunnel waits before it sends a keep alive
message in case it receives no data.
If the tunnel does not receive incoming data during a certain time, it sends a keep
alive message to the other side and waits for an acknowledgement.
l2tpMode Use this element to set the L2TP function of the Telindus 1031 Router.
The
l2tpMode
element has the following values:
Select auto only if you use a Telindus router at both sides of the tunnel. In conjunc-
tion with routers from other vendors (e.g. Cisco), specifically select an L2TP mode
(
lac or lns ).
tunnelAuthentication Use this element to enable ( on ) or disable ( off ) tunnel
authentication.
L2TP incorporates a simple, optional, CHAP-like tunnel authentication system dur-
ing control connection establishment.
If the LAC or LNS wishes to authenticate the identity of the peer it is contacting or
being contacted by, it sends a challenge packet. If the expected response and
response received from a peer does not match, the tunnel is not opened.
To participate in tunnel authentication, a single shared secret has to exist between
the LAC and LNS.
tunnelSecret Use this element to set the tunnel secret. This secret
is used in the tunnel authentication in order to verify
the peer its response.
copyTos Use this element to enable ( on ) or disable ( off ) the cop-
ying of the Type Of Service (TOS) field value of the
packets.
maxNrOfRetrans-
missions Use this element to set the number of times a control
message has to be retransmitted in case no acknowl-
edgement follows, before the tunnel is closed.
