DBG-2000 User Guide With Router (classical routing), devices on the LAN can be directly accessed from the Internet with their public IP addresses (assuming appropriate firewall settings are configured). If your ISP has assigned an IP address for each of the computers/devices you use, select Router. Network address translation (NAT) is a technique that allows several computers and devices on your local network to share an Internet connection. The computers on the LAN use a "private" IP address range, while the WAN port on the gateway is configured with a single "public" IP address. Along with connection sharing, NAT also hides internal IP addresses from the computers on the Internet. NAT is required if your ISP has assigned only one IP address to you. The computers/devices that connect through the gateway will need to be assigned IP addresses from a private subnet. VLAN The gateway supports virtual network isolation on the LAN by using VLANs. You can configure LAN devices to communicate in a sub-network defined by VLAN identifiers. A unique VLAN ID can be assigned for each LAN port so that traffic to and from the physical port can be isolated from the general LAN. VLAN filtering is advantageous to limit broadcast packets of a device in a large network. In the Add VLAN profile page, define the virtual network. VLAN Settings The VLAN settings section displays a list of configured VLANs by name and VLAN ID. A VLAN membership can be created by clicking the Add button present above the list. The cloud gateway supports LAN ports with different subnets for each LAN, i.e., for port 4, the assigned IP address is 192.168.10.1, for port 3, it is 192.168.11.1, and for port 2, it is 192.168.12.1. The VLAN ID value can be any number from 1 to 4094. By default, the cloud gateway accepts only untagged traffic on the LAN interface. Therefore, for any tagged traffic, the user has to add a VLAN explicitly. The fields available on the VLAN settings table are as follows: Field Name VLAN ID Base Interface IP address Subnet mask Captive portal Actions Description It displays the name of the VLAN. It displays the numeric value associated with the VLAN. It displays the physical interface on which the VLAN is created. It displays the IP address for the VLAN. It displays the subnet mask for the VLAN. If the captive portal is enabled on the VLAN, this field displays the name of the captive portal. You can edit or delete the respective VLAN. Note: This field is available only when the "Use profile configuration" field is disabled. Click Add to add a new VLAN. This opens the Add VLAN profile page. To delete multiple entries at once, select the checkboxes of the configured VLANs you want to delete, and click Delete. 59
