Enable NAT checkbox
If the LAN is configured with a private IP address, the user should select this
checkbox. The NAT submenu on the left side main panel will be displayed after
reboot. The user can then configure NAT-related features after the system comes
up. If a private IP address is not used on the LAN side (i.e. the LAN side is using a
public IP), this checkbox should be de-selected. When the system comes back
after reboot, the NAT submenu will not be displayed on the left main panel.
Enable Firewall checkbox
If the firewall checkbox is selected, the Security submenu on the left side main panel
will be displayed after system reboot. The user can then configure firewall features
after the system comes up. If firewall is not used, this checkbox should be
de-selected to free up system resources for better performance. When system
comes back after reboot, the Security submenu will not be displayed on the left
main panel.

like this ADSL router to assign dynamic IP addresses, DNS server and default
gateway to other LAN devices. Select the button Enable DHCP server on the LAN to
enter the starting IP address and end IP address and DHCP lease time.
