L2Tp Server Users - MikroTik RouterOS v2.9 Reference Manual

enabled ( yes | no ; default: no ) - defines whether L2TP server is enabled or not
mtu ( integer ; default: 1460 ) - Maximum Transmission Unit. The optimal value is the MTU of the
interface the tunnel is working over decreased by 40 (so, for 1500-byte Ethernet link, set the MTU
to 1460 to avoid fragmentation of packets)
mru ( integer ; default: 1460 ) - Maximum Receive Unit. The optimal value is the MRU of the
interface the tunnel is working over decreased by 40 (so, for 1500-byte Ethernet link, set the MRU
to 1460 to avoid fragmentation of packets)
authentication ( multiple choice: pap | chap | mschap1 | mschap2 ; default: mschap2 ) -
authentication algorithm
default-profile - default profile to use
Example
To enable L2TP server:
[admin@MikroTik] interface l2tp-server server> set enabled=yes
[admin@MikroTik] interface l2tp-server server> print
enabled: yes
mtu: 1460
mru: 1460
authentication: mschap2
default-profile: default
[admin@MikroTik] interface l2tp-server server>

L2TP Server Users

Home menu level: /interface l2tp-server
Description
There are two types of items in L2TP server configuration - static users and dynamic connections.
A dynamic connection can be established if the user database or the default-profile has its
local-address and remote-address set correctly. When static users are added, the default profile
may be left with its default values and only PPP user (in /ppp secret) should be configured. Note
that in both cases PPP users must be configured properly.
Property Description
name ( name ) - interface name
user ( text ) - the name of the user that is configured statically or added dynamically
mtu - shows client's MTU
client-address - shows the IP of the connected client
uptime - shows how long the client is connected
encoding ( text ) - encryption and encoding (if asymmetric, separated with '/') being used in this
connection
