Users might have much more confidence about the security in the network for data
transmission if the functions of anti-virus and anti-intrusion are activated. The VigorPro
router offers the mechanism of anti-virus and anti-intrusion. What you have to do is to set the
proper profiles and invoke them. The anti-virus profile and anti-intrusion configuration can
be set in Anti-Virus menu (refer to section 3.7) and Anti-Intrusion menu (refer to section 3.6).
However, the mechanism must be enabled either in Firewall>>General Setup or
Firewall>>Filter Setup web page. After you choose proper Anti-Virus profile and check
Anti-Intrusion box, the Anti-Virus and Anti-Intrusion LEDs on the front panel will light up.
Below shows the menu items for Firewall.

General Setup allows you to adjust settings of IP Filter and common options. Here you can
enable or disable the Call Filter or Data Filter. Under some circumstance, your filter set can
be linked to work in a serial manner. So here you assign the Start Filter Set only. Also you
can configure the Log Flag settings, Apply IP filter to VPN incoming packets, and Accept
incoming fragmented UDP packets.
Important: When some packet does not fit the rule configured in Filter Setup web page,
the filtering action configured in general setup web page will apply to that packet.
Click Firewall and click General Setup to open the general setup page.
