General Settings: Firewall
The last subgroup in the General Settings group is Firewall, which contains four pages. The name of the subgroup is quite self-explanatory.
The Access Control page allows blocking access to the router for specific machines not only by MAC addresses but also by IP-addresses, certain protocols, ports, etc.
The URL Blocking page is where you fill in a list of addresses whose data will be blocked by the router. The addresses are specified by means of keywords.
The DoS page allows to block actions associated with DoS attacks.
On the DMZ page you can open any machine on the router’s local network for limitless bidirectional data exchange with the external network.
