Security Level
There are three pre-defined security levels (high, medium, and low)
that contain different security filters for each interface (WAN/LAN,
WAN/DMZ, DMZ/LAN). There is a fourth option called None, which
is a blank firewall configuration that provides no security. Additional
filters can be added to each security level. The default setting is
High
