Data routing through a gateway cluster of a wide area network

A method, comprising:

• generating, at a manager gateway of a gateway cluster of a local area network (LAN), a virtual IP address for each combination of gateway of the gateway cluster and virtual local area network (VLAN) of the LAN;
• receiving, at the manager gateway, an indication that a client device associated with a first VLAN has joined the LAN;
• determining, by the manager gateway, an anchor gateway to which the client device is to be anchored;
• transmitting, from the manager gateway, a first message anchoring the client device to the anchor gateway, wherein anchoring the client device to the anchor gateway comprises establishing a data traffic tunnel between the client device and the anchor gateway, and wherein data traffic forwarded between the gateway cluster and the client device is forwarded via the data traffic tunnel;
• and
• transmitting, from the manager gateway, a second message offering an address to the client device, wherein a gateway address of the second message corresponds to the virtual IP address for the combination of the anchor gateway and the first VLAN, and wherein data traffic originating from the client device is forwarded to a wide area network (WAN) via a WAN uplink terminated at the anchor gateway.

• receiving, at the manager gateway, a second message that offers an IP address to the client device, the second message including a gateway address corresponding to a gateway of the gateway cluster;
• and
• forwarding, from the manager gateway, a modified second message to the client device, wherein the modified second message includes a gateway address corresponding to the virtual IP address for the combination of the anchor gateway and the first VLAN.
