LAN IP
Use the LAN section to configure the LAN IP address for the Gateway and to enable the DHCP
server for dynamic client address allocation. You can also configure the Lease Time for the
DHCP clients on your network.
Private LAN IP Settings
Define the Gateway’s private LAN settings. The IP address configured here is the Gateway’s
(default: 192.168.0.1).
NOTE: Port Forwarding and Access Control rules will be based on the network scope defined
here. If either of these types of rules were previously setup and the Private LAN IP address is
changed, then those rules will need to be recreated to reflect the new Private LAN IP network.
DHCP Server Settings
The Gateway’s DHCP Server can be turned enabled/disabled here. Also the DHCP client Lease
Time can be adjusted from the default One Week setting. The Gateway functions as a DNS
proxy by default. DNS proxy can be disabled by configuring Primary and Secondary DNS values
here, which LAN DHCP clients will receive in their lease.
NAT
Network Address Translation (NAT) allows multiple users at your local site to access the
Internet through a single public IP address.
Port Forwarding
The Gateway supports port forwarding that enables customers to host servers on their LAN.
You can configure this feature to redirect the external service request to the appropriate
internal server and port.
For example, if you are running a WEB server, you can configure all traffic on port 80 to be
redirected to the IP address of the WEB server running on your network.
