Does PlusNet actually have any system protection for Denial of Service Attacks?
It depends what you mean by Denial of Service Attacks.
Typically a DoS attack involves someone on the internet sending a deluge of connection requests on a specific service port at your internet address THAT YOU USE (typically to allow access to a web server or other service on your network) in order to overwhelm the connection to prevent other people accessing the service you are providing - i.e. deny legitimate access to the service.
Alternatively, many firewall logs report "DoS attack" when the firewall has blocked a speculative external port probe in an attempt to detect whether there is anything interesting that could be targeted on your network. This isn't really a "denial of service" but more like someone knocking on your door to check whether anyone is home, and as others have already said, your router is reporting that it is doing its job by hiding and protecting your connection.
@Marvo So at the moment you are describing the firewall in your router that is blocking unsolicited external connections that have reached your home internet connection. Did you know that Plusnet have an additional firewall, that can block the most common port probing BEFORE those requests are passed to your home connection.
To find the Plusnet "Broadband Firewall", login to your "Member Centre" and then go to https://www.plus.net/member-centre/broadband/firewall
You might find a setting there that will help significantly reduce the most common unsolicited port probes.
