VPN: how to limit logins to two from different locations

How can I limit the number of simultaneous logins of a same VPN user from different locations to for example 2 logins. There is an option “only one” under “limits” at “PPP Profile” section which limits the users to single login, but I need to have 2 simultaneous logins for each user possible.

Should I setup RADUIS server? and use its authorization…

Thanks

hi
you can create 2 user with the same user name and password in secret list.

Hi,
But I can’t create two secrets with the same username.
“Could not add new PPP secret - secret with the same name already exists”
