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.
6. Click Next to display the following screen. The Device Setup page allows the
user to configure the LAN interface IP address and DHCP server if the user
would 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.
Note:
If the NAT function is enabled, this DHCP Server Relay won’t be displayed
as an option.
