When the router is delivered, the level of the firewall is set to Standard. Normally, it is
recommended that you set the level of the firewall to Standard. Thus, the network
security can be ensured and most requirements for using the network can be met.
If you have special requirements for using the network, you can set the protective level
as required or define more firewall rules.
Configuration Example
For example, you have stringent requirements on network security. To allow the PCs on a
LAN to only browse Web pages and prohibit Internet users from accessing the router,
you can set the firewall level of the router to High as follows:
Step 1
