Firewall Settings
5.3 IP Filter Setup
The IP filter function is similar to URL Filter. It provides further restrictions in access permission. URL Filter- ing only blocks port number 80 (HTTP) on servers outside of your own network. In IP filtering, you can assign a group of IPs to be restricted. You can block four individual ports or a range of ports at the same time, so the specific group of intranet hosts cannot connect to these ports.
To block IPs using the IP filter, please follow the steps below.
1. Select the “Enable” radio button in the IP Filter.
2. Enter the IP address range in the format “x. x. x. x / x” (e.g. “172.168.1.0/24”, to restrict this IP group)
3. Select the Protocol of the IP you wish to block. If you are unsure, select both.
