How to have a GTM with multiple Listeners where each only replies to specific Wide IPs

Hi,

as we will need to add lots of resolutions, will this work or all the DNS requests will be dropped? Do I need to put a default statement at the end of each "switch" to allow traffic or without a statement it will do the default behavoir of resolving any DNS request to that Listener?

Thanks a lot.

when DNS_REQUEST {
    if { ([IP::local_addr] eq "1.1.1.1")
        switch [DNS::name] { 
            aaa.com { drop }
        } 

    } elseif { ([IP::local_addr] eq "2.2.2.2")
        switch [DNS::name] { 
            bbb.com { drop } 
        } 
    }
}
