It is similar to the DEVICE SETUP screen in Quick Setup, but with more options. NOTE: NAT is disabled above so UPnP is hidden (see underlined notes below). Consult the field descriptions below for more details. 47 IP Address: Enter the IP address for the LAN port. This option is hidden when NAT disabled or if no PVC exists Enable IGMP Snooping: Enable by ticking the checkbox. DHCP Server: To enable DHCP, select Enable DHCP server and enter starting and ending IP addresses and the leased time. This setting configures the router to automatically assign IP, default gateway and DNS server addresses to every PC on your LAN. DHCP Server Relay: Enable with checkbox and enter DHCP Server IP address. This allows the Router to relay the DHCP packets to the remote DHCP server. This option is hidden if NAT is enabled Configure the second IP address by ticking the checkbox shown below. Subnet Mask: Enter the secondary subnet mask for the LAN port. NOTE: The Save button saves new settings to allow continued configuration while the Save/Reboot button not only saves new settings but also reboots the device to apply the new configuration (i. e. all new settings). 6. 3 NAT To display this option, NAT must be enabled in at least one PVC shown on the Advanced Setup - WAN screen. (NAT is not an available option in Bridge mode) 48 6. 3. 1 Virtual Servers Virtual Servers allow you to direct incoming traffic from the WAN side (identified by Protocol and External port) to the Internal server with private IP addresses on the LAN side. The Internal port is required only if the external port needs to be converted to a different port number used by the server on the LAN side. A maximum of 32 entries can be configured. To add a Virtual Server, click the Add button. The following screen will display. Select a Service User should select the service from the list. 49 Or Custom Server Server IP Address External Port Start External Port End Protocol Internal Port Start Internal Port End Or User can enter the name of their choice.
