Scenario 3: transporting VLANs through a GRE tunnel with VLAN filtering
Before you start this configuration, do note that:
- This configuration does not allow routing between VLANs transported in the GRE tunnel. If your configuration requires routing between VLANs, refer to Scenario 2.
- A bridge is needed for each VLAN transported. It is therefore essential that you ensure the firewall supports the number of bridges planned.
- Associating a bridge to a VLAN makes it possible to filter VLANs through the tunnel – only VLANs associated with bridges are allowed to go through the tunnel.
