4.9 Firewall

A firewall is a set of related programs that protects the resources of a private network from
other networks. It prevents hackers to access your private data resource.
There are three security levels: basic firewall security, automatic firewall security and
advanced firewall security.
4.9.1 Basic Firewall Security
Check Basic Firewall Security.
This level only enables the NAT firewall and the remote management security. The NAT
firewall will take effect when NAT function is enabled. The remote management security by
default will 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.
Press Finish to finish setting of firewall and review the parameters.
