hi
this mean’s that pptp request to this router in termination step is faild.
maybe username or password is incorrect or vpn type not correct or … .

3

so, someone is trying to access my router from the internet?

How do I prevent this from happening? I have already disabled all IP services except winbox access.

4

Add suitable rules in ip firewall input chain to block new connections for unwanted sources and destination ports
