What Does This Block Of Text Mean In My Syslog?

[Craigy R1]

Hi guys, I've had syslog enabled on a new Draytek router for a few weeks now and it's the first time I've noticed this block of text. What does it mean in plain English? Looks suspicious to me.

Looks like someone is trying to access your device via Point-to-Point Protocol (PPP)

Strange because it happened 3 days after finishing conversing with Draytek support after giving them a detailed syslog. Coincidence or something more sinister? 

Do you know what setting or where the setting is in the Vigor2862 to stop these sort of attempts?

Could be just anonymous Internet trollbots looking for open vulns.

The best setting to check is to make sure you have the default admin username and password changed as much as possible. You can write them down on a paper and tape it to your device, as hackers can't yet get inside your house to read notes taped to your gear.
