Suddenly I have encountered the weirdest problem, my synology NAS 1515+ will deny all my VPN clients.
This was working fine until today, and the only things I have done is swithching the server from LAN1 -> LAN2 port. But all firewall rules and forwards are enabled. I even tried creating a new user with a simple password, but the same, my authentication is rejected. "your name or password was incorrect"
Anyone have any idea about what is going on???? I am 100% certain I am typing it correct, and I have checked that it is only the guest user that does not have any privilieges for VPN.
Hope someone can help.
