    Hi Dinesh,

    Good day and thanks for reaching out to Sophos Community. Hope you're well.

    Few queries:

    -Did you configure this ISP to a new interface and used it after the upgrade? or prior upgrade this was already your ISP and working with no issues?

    -Do you have alias IPs on the Airtel ISP interface on Sophos Firewall?

    -When ISP/internet goes down, can you confirm if FW still can ping and has connectivity to public?

    -Can you also share ARP neighbor on Configure>Network>Show>Ipv4 neighbor cache (if it has entries of the upstream router ISP)

    Also, kindly respond to Vivek's recommendation and let us know the outcome. I may recommend you as well to open a support ticket if none of the recommended steps would work so it can be further checked by an engineer. Then kindly share with us the would-be generated caseID via DM or by replying to this thread.

    Thanks for your time and patience, and thank you for choosing Sophos

    Cheers,
