Wireless-N Gigabit Router with Storage Link
The Security Tab - Firewall
The
Firewall
screen offers a firewall and filters that block specific Internet data types.
Firewall
Firewall Protection
. A firewall enhances network security and uses Stateful Packet Inspection (SPI) for more
detailed review of data packets entering your network. Select
Enabled
to use a firewall,
or
Disabled
to disable it.
Internet Filter
Filter Anonymous Internet Requests
. When enabled, this feature keeps your network from being “pinged,” or
detected, by other Internet users. It also hides your network ports. Both make it more difficult for outside users to
enter your network. This filter is enabled by default. Select
Disabled
to allow anonymous Internet requests.
Filter Multicast
. Multicasting allows for multiple transmissions to specific recipients at the same time. If
multicasting is permitted, then the Router will allow IP multicast packets to be forwarded to the appropriate
computers. Select
Enabled
to filter multicasting, or
Disabled
to disable this feature.
Filter Internet NAT Redirection
. This feature uses port forwarding to block access to local servers from local
networked computers. Select
Enabled
to filter Internet NAT redirection, or
Disabled
to disable this feature.
Filter IDENT (Port 113)
. This feature keeps port 113 from being scanned by devices outside of your local
network. Select
Enabled
to filter port 113, or
Disabled
to disable this feature.
Web Filter
Proxy
. Use of WAN proxy servers may compromise the Gateway's security. Denying Filter Proxy will disable
access to any WAN proxy servers. To enable proxy filtering, click the checkbox.
Java
. Java is a programming language for websites. If you deny Java, you run the risk of not having access to
Internet sites created using this programming language. To enable Java filtering, click the checkbox.
ActiveX
. ActiveX is a programming language for websites. If you deny ActiveX, you run the risk of not having
access to Internet sites created using this programming language. To enable ActiveX filtering, click the checkbox.
Cookies
. A cookie is data stored on your computer and used by Internet sites when you interact with them. To
enable cookie filtering, click the checkbox.
