ADVANCED NETWORK
Advanced Network
This device supports advanced network features, such as Firewall, QoS, Security, Redundancy, and Management.
Firewall
The firewall function includes Packet Filters, URL Blocking, MAC control, and Options.
Packet Filters
Packet filters include outbound and inbound filters. This enables you to control what packets are allowed to pass
through the router. You can select two filtering policies:
■ Allow all to pass, except those match the specified rules.
■ Deny all to pass, except those match the specified rules.
Enabling the Log Alert will record events that are blocked by these rules.
You can specify rules for each direction, inbound or outbound. For each rule, you can define the following:
■ Source IP address or range. You can define a single IP address or a range of IP addresses. Leaving this
empty implies all IP addresses.
■ Destination IP address or range.
■ Destination Port: You can define a single port or a range of ports.
■ Protocol: TCP, UDP, or both.
■ Use Rule Schedule #.
Each rule can be enabled or disabled individually.
URL Blocking
URL blocking blocks websites containing pre-defined keywords. This feature filters both domain input suffix and
keywords.
■ URL Blocking: Check to enable URL Blocking.
■ Black List/White List: Choose one of the following conditions:
■ Allow all to pass, except those match the specified rules.
■ Deny all to pass, except those match the specified rules.
■ Log Alert: Check to enable Log Alert. This will record events that are blocked by these rules.
■ Invalid Access Web Redirection: Users will see a specific webpage to know their access is blocked by a rule.
■ URL: If any part of the website's URL matches the pre-defined word, the connection will be blocked. Up to
10 pre-defined words in a rule and each URL keyword separated by a comma can be entered.
■ Schedule: The rule can be turned off according to a schedule rule.
■ Enable: Check to enable each rule.
MAC Control
Mac Control allows you to assign different access rights for different users based on a device's MAC address.
