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.
