Multiple VLAN Subnets

Typically, VLANs are isolated such that the traffic generated by any one of these
networks is not seen by the others. However there are instances where you want
to enable communication between VLANs. When you configure VLAN subnets, the
security appliance routes traffic between VLANs and provides services such as a
DHCP server for the members of each VLAN.
Click Networking on the menu bar, and then click VLAN > Multiple VLAN
Subnets in the navigation tree.
The Multiple VLAN Subnets page appears. All VLANs from the Networking > LAN
> Available VLANs page appear in the List of available Multiple VLAN Subnets
table.
The Multiple VLAN Subnet Configuration page appears.
In the Multiple VLAN Subnet section of the page, enter the following settings:
• IP Address: Enter the VLAN subnet IP address.
• Subnet Mask: Enter the subnet mask for this VLAN.
In the DHCP section of the page, choose the DHCP mode:
• None: Choose this option if you do not want to enable a DHCP server for this
VLAN.
• DHCP Server: Choose this option to allow the security appliance to act as a
DHCP server for this VLAN. If you choose this option, complete the other
fields in this section of the page.
