Who is trying to connect to my VPN?

[nphansen]

I have an RT-N66U router with VPN enabled. I regularly (about once a day) see the following in the log:

Oct 3 10:51:46 pptpd[8758]: CTRL: EOF or bad error reading ctrl packet length.
Oct 3 10:51:46 pptpd[8758]: CTRL: couldn't read packet header (exit)
Oct 3 10:51:46 pptpd[8758]: CTRL: CTRL read failed

I have read similar posts about this issue. E.g.

In the logs above, there is also an IP address. E.g. probably someone is trying to log in or doing a portscan etc. But I'm not seeing that. Only the above three CTRL lines.

So are these also 'just' someone portscanning or trying to log in to my VPN?

Just port scanning without actually trying to log on.
