NETWORK WEB FILTER RULES
Domain / URL filter rules allow you to control
access from your network to any external domain
or website. Rules are assigned to a specific LAN
network and the highest priority rule will have
precedence when there is a conflict. Addresses can
be added by URL/Domain name or by IP address.
IP address ranges can be filtered by using CIDR
notation, e.g. 4.2.2.2/24.
Exceptions to existing rules can be created by
adding another rule with higher priority. For
example if access to maps.example.com is desired,
but example.com is blocked with a priority of 50.
The addition of an allow rule for maps.example.
com with a priority of 49 or less will allow access.
When creating rules keep in mind that some sites
use multiple domains so each domain may need a
rule added to produce the desired behavior.
To add a Network Web Filter Rule, click Add.
Default Network Filter Settings
When a network is set to Allow (Blacklist) it will
allow access to those sites not blocked in the
Filter Rules. Selecting Block (Whitelist) will only
allow access to websites with an Allow action in
the Filter rules, all other sites will be blocked.
Selecting to Filter URLs by IP Address will cause
the router to perform a DNS lookup on URL entries
and the IP addresses will be appended to the
appropriate block/allow list. This can have side
effect of being very strict and sites that are hosted across many domains may need every domain added the list
for full functionality.
The settings can be changed by selecting a network and clicking the Edit button.
