Hi all,

I am using a windows xp laptop trying to connect to a MT router through a L2tp tunnel.I face difficulties of setting it up. I refer to the "http://wiki.mikrotik.com/wiki/Manual:In ... ck_example" under remote client.

The different between my setup and the picture is my windows xp laptop is directly connected physically to the MT router instead of through the internet. So i guess the different of setting it up should not be too big.

According to the document, i set ether1 ip as 192.168.80.1 and ether2 ip as 10.1.101.1. I set my laptop ip add as 10.1.101.100. After that i use the New Connection Wizard to create a new connection, host is 192.168.80.1, but i got a error, unable to eastablish the vpn connection.

Can anyone help me out? Anything i did wrongly? Any very detailed working example?

Please help me thanks a lot. Been stuck for quite some time and try alot of others configuration but still unable to make it.

Thank you very much.

Windows L2TP is used together with IPSec. You have to modify windows registry to allow only L2TP.

To disable IPSec: on XP, locate
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\Parameters
Add new DWORD Value named ProhibitIpSec, set to 1 , Restart the computer.

Hi all, thanks for the reply. I actually tried that before, but i will try again and get back here again.

What should i set my laptop IP address? and the host i set to 192.168.80.1 is it correct?

Thank you.
