Configure ER605, so that some devices can only use one particular WAN interface
I am new to networking and trying to setup my small office.
Setup
I have two Internet connections
.
Wan1: Airtel (PPoE)
Wan2: BSNL (DynamicIP), it is airfiber connection and comes with its own router.
Lan ports: 3,4& 5 Lan ports are connected to different networks
Lan Port 3: Configured VLan 20 for Office (Untagged)
Lan Port 4: Configured VLan 21 for Guest (Untagged)
Lan Port 5: Configured VLan 22 for Cameras (Untagged)
Load balancing is not enabled as BSNL connection is not stable (Airfiber). it is only used as backup or failover
I have 2 home routers and a POE switch as well. (TP-Link Archer and D-Link)
Lan port 3 -VLan 20 is connected to TP-Link Archer router for Office use.
Lan Port 4 - VLan 21 is connected to D-Link router for Guest
Lan Port5 - Vlan 22 is connected to POE switch to NVR (unmanaged)
Till here everything works fine and no issue with the network.
I want Vlan 20 (lan port3) to connect to Wan1 (Airtel) and use BSNL (Wan2) in case Airtel goes down.
I want Vlan 21 (lan port4) to connect to Wan2 (BSNL) only. even if the Wan2 connection is down, it should not use failover.
I want Vlan 22 (lan port5) to use either, as failover is in place.
Please advise.
