Message <888>: user 123456 authentication failed
There are 3 or 4 daily from different users (user 0, vpn, pptp). I have confinfigured pptp vpn for access on to my server (working without problem). I have susspect someone try reach my network via pptp protocol. Am I right? I configured this protocol because its user friendly to use on new device but If I am right I ll change it on the open VPN (with cert). Thank you so much for answer.
