Vigor Routers provide multiple IP subnets, which allows different groups of LAN clients to use different ranges of IP addresses. More IP subnets are available when VLAN (Virtual LAN) is configured to partition the LAN clients.
Use following steps to configure multiple subnets with port-based VLAN.
1. Edit the default 802.1Q VLAN ID 10 via LAN >> Switch >> 802.1Q VLAN as follows:
a. In Member, de-select LAN_Port_2, LAN_Port_3 and LAN_Port_4, leave only LAN_Port_1
b. In Untag, de-select LAN_Port_2, LAN_Port_3 and LAN_Port_4, leave only LAN_Port_1
c. Apply the settings.
2. Add a new 802.1Q VLAN via LAN >> Switch >> 802.1Q VLAN. Edit the profile as follows:
a. Enter VLAN ID as 11
b. Select LAN_Port_2 as Member
c. Select LAN_Port_2 as Untag
d. Apply the settings.
3. Add two more 802.1Q VLAN groups for VLAN ID 12 and VLAN ID 13 following the same steps. After completing the above configurations, there will be 4 VLAN groups.
4. Add a new LAN profile with VLAN ID 11 via LAN >> General Setup page. Edit the profile as follows:
a. Input LAN Profile Name
b. Input the VLAN ID
c. Input the LAN IP address as 192.168.2.1
d. Input DHCP Server Start IP and End IP as 192.168.2.x
e. Apply the configuration
5. Similarly, add two more LAN profiles for VLAN ID 12 and VLAN ID 13. Upon completion, the router will have 4 LAN profiles. When a PC connects to LAN Port 1, it will obtain IP 192.168.1.x. When connected to LAN Port 2, it will obtain IP 192.168.2.x. LAN Port 3 – IP 192.168.3.x, and LAN Port 4 – IP 192.168.4.x. By default, the PCs connecting to different LAN ports cannot access each other because they belong to different VLANs.
