If the LAN is configured with a private IP address, the user should select this
checkbox. The NAT submenu will be displayed on the advanced setup menu 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 menu. The
default setting for MER is disabled.
Enable Firewall checkbox
If the firewall checkbox is selected, the security submenu will be displayed on the
advanced setup menu after 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 menu. The default setting for MER is disabled.
