9.2. Virtual LAN (VLAN) 59 Example: Configure a VLAN Interface in D-Link Firewall This example shows how to configure a VLAN interface. WebUI : 1. Create VLAN interface. Interfaces → VLAN → Add → VLAN: Enter the following: General Name: Type a name for the VLAN interface. Interface: Select the Ethernet interface to use. VLAN ID: Select a suitable VLAN ID. Two VLANs cannot have the same VLAN ID if they are defined on the same Ethernet interface. (The same ID will have to be used on the terminating side.) Address Settings IP Address: Select the IP address this VLAN interface should use. If not configured, the IP of the Ethernet interface will be used. (Optional) Network: Select the network for this VLAN interface. (Optional) Default Gateway: Select the default gateway for this VLAN interface. (Optional) Then click OK 9.2.4 Using Virtual LANs to Expand Firewall Interfaces Virtual LANs are excellent tools for expanding the number of interfaces in D-Link Firewalls. The D-Link Firewalls with gigabit Ethernet interfaces can easily be expanded with 16 new interfaces by using a 16-port Ethernet switch with gigabit uplink port and Virtual LAN support. The process outlined below describes the steps required to perform an interface expansion. Please note that the specific configuration of switch and firewall is highly model dependent and outside the scope of this documentation. • Connect the gigabit uplink port of the switch to one of the gigabit D-Link Firewalls User's Guide
