Allied Telesis AT-WR4500 manual Pptp Users, PPTPTunnel Interfaces, To enable Pptp server

182	AT-WR4500 Series - IEEE 802.11abgh Outdoor Wireless Routers
	RouterOS v3 Configuration and User Guide

￿

Specifying MRRU means enabling MP (Multilink PPP) over single link. This protocol is used to split big packets into smaller ones. Under Windows it can be enabled in Networking tag, Settings button, "Negotiate multi-link for single link connections". Their MRRU is hardcoded to 1614. This setting is usefull to overcome PathMTU discovery failures. The MP should be enabled on both peers.

Example

To enable PPTP server:

[admin@AT-WR4562] interface pptp-server server> set enabled=yes

[admin@AT-WR4562] interface pptp-server server> print enabled: yes

mtu: 1460

mru: 1460

authentication: mschap2,mschap1 keepalive-timeout: 30

default-profile: default [admin@AT-WR4562] interface pptp-server server>

8.7.5 PPTP Users

Description

The PPTP users are authenticated through a RADIUS server (if configured), and if RADIUS fails, then the local PPP user databese is used. See the respective manual sections for more information:

•RADIUS client

•PPP User AAA

8.7.6 PPTPTunnel Interfaces

Submenu level: /interface pptp-server

Description

There are two types of interface (tunnel) items in PPTP server configuration - static users and dynamic connections. An interface is created for each tunnel established to the given server. Static interfaces are added administratively if there is a need to reference the particular interface name (in firewall rules or elsewhere) created for the particular user. Dynamic interfaces are added to this list automatically whenever a user is connected and its username does not match any existing static entry (or in case the entry is active already, as there can not be two separate tunnel interfaces referenced by the same name). Dynamic interfaces appear when a user connects and disappear once the user disconnects, so it is impossible to reference the tunnel created for that use in router configuration (for example, in firewall), so if you need a persistent rules for that user, create a static entry for him/her. Otherwise it is safe to use dynamic configuration.

￿

In both cases PPP users must be configured properly.

Property Description

client-address(read-only: IP address) - shows the IP address of the connected client

encoding (read-only: text) - encryption and encoding (if asymmetric, separated with '/') being used in this connection

mru (read-only: integer) - client's MRU

mtu (read-only: integer) - client's MTU name (name) - interface name

uptime (read-only: time) - shows how long the client is connected

user (name) - the name of the user that is configured statically or added dynamically
