Physical VLAN Connection with VLAN
The illustration below shows the connections for a typical NetDefendOS VLAN scenario.
Figure 3.1. VLAN Connections
With NetDefendOS VLANs, the physical connections are as follows:
•
One of more VLANs are configured on a physical NetDefend Firewall interface and this is
connected directly to a switch. This link acts as a VLAN trunk. The switch used must support
port based VLANs. This means that each port on the switch can be configured with the ID of the
VLAN or VLANs that a port is connected to. The port on the switch that connects to the firewall
should be configured to accept the VLAN IDs that will flow through the trunk.
In the illustration above the connections between the interfaces if1 and if2 to the switches
Switch1 and Switch2 are VLAN trunks.
•
Other ports on the switch that connect to VLAN clients are configured with individual VLAN
IDs. Any device connected to one of these ports will then automatically become part of the
VLAN configured for that port. In Cisco switches this is called configuring a Static-access
VLAN.
On Switch1 in the illustration above, one interface is configured to be dedicated to VLAN2 and
two others are dedicated to VLAN1.
The switch could also forward trunk traffic from the firewall into another trunk if required.
•
More than one interface on the firewall can carry VLAN trunk traffic and these will connect to
separate switches. More than one trunk can be configured to carry traffic with the same VLAN
ID.
