Hello Community Members

 

I am using 2 ISPs: Airtel and N-Tel. Both are on different V-Lans and have their own ONTs. I have one switch as per the mentioned model number. Currently, I have connected the N-Tel ONT to the switch via a LAN cable, and the LAN devices are connected to the N-Tel Network. Wi-Fi, some are using Airtel, and some N-Tel. I want to configure N-Tel and Airtel on the same switch so that, in the event of a failure, another ISP takes over and provides uninterrupted internet to all connected devices. How can I do this? Please guide.

 

One important point is that both have different Static IPs and the same subnets.

I may be wrong but I believe that only the Omada gateways can do the automatic failover that you are looking for.

  @jra11500 Thanks, but I am unable to understand. Kindly advise in simple language. What do you mean by OMADA Gateway?

Gateway = Router

 

Switches are not routers.  Switches can do very basic L3 forwarding using static routes, but not actual ISP failover, NAT etc, you need a gateway for that

Hello, Can you suggest the following 1. India Airtel ISP using Nokia ONT limitation that when I connect the patch cable to the TP-Link Router, all LAN ports stop working, and the second limitation is that they can only do 5 port forwarding, which is less. 2. India N-Tel ISP using TP-Link XX530V ONT, and I can fully control the network, and NAT and Port Forwarding are under my control. 3. TP-Link TP-Link POE 8 Port Full Giga TL-SG2210P is connected to 1 ISP at a time We want to connect 2 ISPs to a single WAN Router, or any mechanism that allows me to utilise the same setup and control my network, such as load balancing, but the users should use only 1 static IP from either ISP. Secondly, I want to control all my TP-Link devices using the switch mentioned above. I am not a network specialist, so I can't provide more details. Please suggest the model numbers of the devices that need to be procured
