Vulnerability Check tool
The Vulnerability Check tool is used to check for the router setup and find open ports via UPnP and NAT-PMP that may lead to external access, and close them. There are 65535 ports on your router but don’t worry, they are not all permanently open.
Secure ports are either opened manually by the owner of the network or, like with a lot of consumer-grade routers, by inbuilt protocols, such as UPnP and NAT-PMP.
These protocols are designed to save users the effort of having to manually open ports – they give permission to the devices within the network to open ports on their own.
The test scans the Internal Router Audit which checks the router addresses, the NAT configuration and whether or not UPnP or NAT-PMP is activated.
With the Vulnerability Check, you can see where your router leaves you vulnerable to hacking. This allows you to make the changes required to toughen up your network security against incoming threats.
