Field
Description
incoming tunnel setup message from the LAC.
Remote Hostname
Enter the host name of the LNS or LAC.
• LAC: Defines the value for Local Host Name of the LNS
(contained in the SCCRQs received from the LNS and the
SCCRPs received from the LAC). The Local Host Name con-
figured in the LAC must match the Remote Host Name con-
figured for the intended profile in the LNS and vice versa.
• LNS: Defines the Local Host Name of the LAC. If the Re-
mote Host Name field remains empty on the LNS, the related
profile qualifies as the standard entry and is used for all in-
coming calls for which a profile with a matching Remote Host
Name can be found.
Password
Enter the password to be used for tunnel authentication. Au-
thentication between LAC and LNS takes place in both direc-
tions, i.e. the LNS checks the Local Hostname and the Pass-
word contained in the SCCRQ of the LAC and compares them
with those specified in the relevant profile. The LAC does the
same with the fields of the SCCRP of the LNS.
If this field remains empty, authentication data in the tunnel
setup messages are not sent and are ignored.
Fields in the LAC Mode Parameters menu
Field
Description
Remote IP Address
Enter the fixed IP address of the LNS used as the destination
address for connections based on this profile.
The destination must be a device that can behave like an LNS.
UDP Source Port
Enter how the port number to be used as the source port for all
outgoing L2TP connections based on this profile is to be be de-
termined.
By default, the Fixed option is disabled, which means that ports
are dynamically assigned to the connections that use this pro-
file.
If you want to enter a fixed port, enable the Fixed option. Select
this option if you encounter problems with the firewall or NAT.
