    networksetup -setstreamingproxystate "$NETWORK_SERVICE_NAME" on
    networksetup -setwebproxystate "$NETWORK_SERVICE_NAME" on

    echo "Disabling HTTP and HTTPs proxy for $NETWORK_SERVICE_NAME"
    networksetup -setstreamingproxystate "$NETWORK_SERVICE_NAME" off
    networksetup -setwebproxystate "$NETWORK_SERVICE_NAME" off
    networksetup -setsecurewebproxystate "$NETWORK_SERVICE_NAME" off
