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

Example
