Hi,

i try to connect my network to VPN server on the internet. VPN-server is a windows server 2025. I use the same credentials from my windows client to connecto to the server. From windows it works fine, from omada i got a log

[Failed]Router: L2TP administrator failed to connect to the server because authentication failed with the wrong username or password.

 

on the server i got these log

CoId={NA}: The following error occurred in the Point to Point Protocol module on port: VPN3-127, UserName: administrator. The connection was prevented because of a policy configured on your RAS/VPN server. Specifically, the authentication method used by the server to verify your username and password may not match the authentication method configured in your connection profile. Please contact the Administrator of the RAS server and notify them of this error.

 

There is nothing to define in omada. What do i need to setup on the server - or is ther no option to connect from omada to windows server vpn?

 

Thanks!

Matze

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

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 but you can check your server settings for that.

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. There aren't many settings you can do on the router so you'll probably have to look at your server to solve the problem.
