Asus RTAC68U manual General, URL Filter, To set up basic Firewall settings

4.6 Firewall

The wireless router can serve as a hardware firewall for your network.

NOTE: The Firewall feature is enabled by default.

4.6.1 General

To set up basic Firewall settings:

1.From the navigation panel, go to Advanced Settings > Firewall > General tab.

2.On the Enable Firewall field, select Yes.

3.On the Enable DoS protection, select Yes to protect your network from DoS (Denial of Service) attacks though this may affect your router’s performance.

4.You can also monitor packets exchanged between the LAN and WAN connection. On the Logged packets type, select Dropped, Accepted, or Both.

5.Click Apply.

4.6.2 URL Filter

You can specify keywords or web addresses to prevent access to specific URLs.

NOTE: The URL Filter is based on a DNS query. If a network client has already accessed a website such as http://www.abcxxx.com, then the website will not be blocked (a DNS cache in the system stores previously visited websites). To resolve this issue, clear the DNS cache before setting up the URL Filter.
