Are you sure that the table lookup is returning an empty value on the HTTP virtual server? 

 

You could add a logging before the IF in the HTTP iRule. 

when HTTP_REQUEST {
    set client_ip [IP::client_addr]
    set msisdn [table lookup -subtable "ip2msisdn" $client_ip]

    log local0. "IP $client_ip MSIDSN $msisdn"

    if { $msisdn ne "" } {
        HTTP::header insert "X-MSISDN" $msisdn
        HTTP::header insert "X-Auth-Status" "AUTHORIZED"
    } else {
        HTTP::header insert "X-Auth-Status" "UNKNOWN"
        HTTP::header insert "X-MSISDN" "NOT_FOUND"
    }    

}
