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.
Available settings are explained as follows:
Item Description
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.

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
For the sake of security, the router will execute strict security
checking for data transmission.
Such feature is enabled in default. All the packets, while
transmitting through Vigor router, will be filtered by firewall.
