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.
Click Firewall and click General Setup to open the general setup page.
Call Filter
Check Enable to activate the Call Filter function. Assign a
start filter set for the Call Filter.
Data Filter
Check Enable to activate the Data Filter function. Assign a
start filter set for the Data Filter.
Accept large incoming…
Some on-line games (for example: Half Life) will use lots of
fragmented UDP packets to transfer game data. Instinctively
as a secure firewall, Vigor router will reject these fragmented
packets to prevent attack unless you enable “Accept large
incoming fragmented UDP or ICMP Packets”. By checking
this box, you can play these kinds of on-line games. If
security concern is in higher priority, you cannot enable
“Accept large incoming fragmented UDP or ICMP
Packets”.
Enable Strict Security
Firewall
Check the box to enable such function.
All the packets, while transmitting through Vigor router, will
be filtered by firewall settings configured by Vigor router if
such feature is enabled. If the firewall system does not have
any response (pass or block) for these packets, such as no
response coming from web content filter, then the router’s
firewall will block the packets directly.
