    Hello Nabin,

    Thank you for contacting the Sophos Community.

    Most likely you have more than two tunnels configured for Remote Gateways with * instead of an IP, here is an extract of the documentation on this:

    You can use a wildcard when the remote firewall has a dynamic IP address.
    If you specify a wildcard IP address (*), you can't set Gateway type to Initiate the connection because Sophos Firewall won't know with whom to connect.
    If you want to enter a wildcard address (*), we recommend the following:

    • Gateway type: Respond only
    • Remote gateway uses a dynamic IP address.
    • Authentication type: Don't use a preshared key.


    You must use the same preshared key for all IPsec connections that use a wildcard remote gateway address on the firewall.
    You can't use * for tunnel interfaces.

    Regards,
