PPTP and Windows XP, cannot use encryption

RouterOS General
1

According to Mikrotik Manual it supports both 64 and 128 bit encruption with PPTP.

I want to connect remote computer using PPTP so I set it up as suggested in manual and other sources. Connection is ok but only if i turn off Requre data encryption. If it os on, i get Error 742: The remote computer does not support requred data encryption type.

Is this something wrong with the settings I made or data encryption between XP and MT is not possible? I could not find any option to set about PPTP encryption in MT.

PPTP server in MT is set to use mschap1 and mschap2 only which is default.

Would you mind to share with us your configuration? See, I’m not a telepathist, nor others on this forum are to say if it is a configuration problem without seeing the configuration. :wink:

My Windows XP client cannot connect to the PPPoE server

You have to specify the “Service Name” in the properties of the XP PPPoE client. If the service name is not set, or it does not match the service name of the MikroTik PPPoE server, you get the “line is busy” errors, or the system shows “verifying password - unknown error”

Check that, also, I’m not sure that the XP PPPoE client supports encyrption, but I could be wrong.. Or maybe it was that you can’t use encryption and compression at the same time.. I can’t recall exactly, but some things to look into..

I believe the question was about PPTP not PPPoE. Anyway, when you added the user did you change the default profile?

/ppp profile

0 * name=“default” local-address=0.0.0.0 remote-address=0.0.0.0
session-timeout=0s idle-timeout=0s use-compression=no
use-vj-compression=no use-encryption=no require-encryption=no
only-one=no change-tcp-mss=yes tx-bit-rate=0 rx-bit-rate=0
incoming-filter=“” outgoing-filter=“” dns-server=“” wins-server=“”

Note the “use-encryption=no”. When I have PPTP connectivity issues like yours, this is most often the issue.
