10.16.9.1 Firewall security level
There are three levels of firewall, which you can setup in this product.
Level one, basic, only enables the NAT firewall and the remote management security. The
NAT firewall will take effect if NAT function is enabled. The remote management security is
default to block any WAN side connection to the device. Non-empty legal IP pool in ADMIN will
block all remote management connection except those IPs specified in the pool.
Level two, automatic, enables basic firewall security and all DoS protection.
Level three, advanced, is an advanced level of firewall where user can determine the security
level for special purpose, environment, and applications by configuring the DoS protection and
defining an extra packet filter with higher priority . Note that, an improper filter policy may
degrade the capability of the firewall and/or even block the normal network traffic.
The firewall security level can configure via level command.
