Hi all,

we decided to turn our OpenVPN server from a windows machine to one of our mikortik router.

The implementation was much more difficult from the windows machine, I have to say!

Anyway, the only clients we cannot connect anymore are our Grandstream IP Phones.

can you please help me how to turn of the requirement from the clients to provide a username/password?

This was not happening when OpenVPN server was on the Windows machine. Other clients can provide, but not the Grnastreams ones..

So is it possible?

No it is not possible.
You can find all limitations listed in the manual.

Thnks for the reply.

Just to make sure I understand correctly reading the manual:

Authentication without username/password is not possible for ANY type of client OR just wben client is a mikrotik router?
