You can try this combination, it will not display the content if the source IP address is defined in your data group.

Notice the 'not' (!) in the if statement used in the default section of the switch. 

when HTTP_REQUEST {
    if {[active_members [LB::server pool]] < 1 } {
        switch [HTTP::uri] {
            "/mylogo.png" {
                HTTP::respond 200 content [ifile get "mylogo.png"]
            }
            default {
                if {!([class match [IP::addr [IP::client_addr]] equals "private_net"])} {
                    HTTP::respond 200 content {
                        <!doctype html>
                        <title>Site Maintenance</title>
                        <style>
                        body { text-align: center; padding: 150px; }
                        h1 { font-size: 50px; }
                        body { font: 20px Helvetica, sans-serif; color: #333; }
                        article { display: block; text-align: left; width: 650px; margin: 0 auto; }
                        a { color: #dc8100; text-decoration: none; }
                        a:hover { color: #333; text-decoration: none; }
                        </style>
