Matze78 wrote mschapv2 is activated by default. i have no idea what i need to setup... @Matze78 have you just enabled mschapv2? do you have an option for require mschapv2 i think you have to require...

@Matze78 I don't know windows server, but I did a test here against an l2tp server I have, I disabled mschapv2 and then I couldn't log in.. but if it's enabled on yours I don't have any more tips....

@Matze78 I used l2tp previously and on ER8411 I had problems logging in, the solution was to enable Require Strong Authentication (mschapv2) on the server I connected to, it was not a windows server...

@Matze78 maybe you should use ad-name\username as your username

@ODCI-IT check the network cable

@Sadiqus yes it looks correct now, so if you don't have any ACL blocking it it should work. if it doesn't work now then contact your ISP, maybe they have blocked something.
