To establish a connection over an L2TP/IPsec tunnel, both the
LNS device and the LAC device must be configured. To
configure the LNS device, use
set l2tp-lns:
# set l2tp-lns
EnableL2TP (Y|N to enable|disable L2TP/IPSec LNS support):
y
LocalAddress (IP address of LNS local PPP interface):
<lnsIPaddr>
LACIpRangeMin (Start IP for LACs IP address range):
<minIPaddr>
LACIpRangeMax (End IP for LACs IP address range):
<maxIPaddr>
Enter
y
or
n
to enable or disable the L2TP server functionality.
This setting applies to all interfaces on the Mesh Point.
In
LocalAddress, enter the IPv4 address of the Point -to-Point
Protocol (PPP, or PtP) interface on the L2TP server.
In the
LACIpRangeMin field, enter the beginning of the range of
IP addresses from which this server will accept L2TP tunnel
connection requests. In the
LACIpRangeMax field, enter the end
of the that range of IP addresses.
Alternatively, you can execute
set l2tp-lns
non-interactively
with valid switches and arguments in any order:
# set l2tp-lns -enable y|n -localaddr
<LocalIPAddress>
-iprangemin
<BeginIPAddr>
-iprangemax
<EndIPAddr>
To configure the (ES210) LAC device, use set l2tp-lac:
# set l2tp-lac
EnableL2TP (Y|N to enable|disable L2TP/IPSec LAC support):
y
DestAddress (IP address of LNS to connect with):
<lnsIPaddr>
Key (name of the private key & client certificate to use for L2TP authentication):
Enter
y
or
n
to enable or disable the L2TP server.
In
DestAddress, enter the IPv4 address the LNS. This is the
same address entered in
LocalAddress with set l2tp-lns.
Enter the name of the key pair/ certificate to use for EAP-TLS
user authentication.
Alternatively, you can execute
set l2tp-lac
non-interactively
with valid switches and arguments in any order:
# set l2tp-lac -enable y|n -lnsaddr
<LNSAddress>
-key <keyname>|-nokey
Use the -
key
switch to indicate or change the key pair/
certificate to use for EAP-TLS user authentication.
Use the -
nokey
switch to clear the encryption key currently in
use.
