Reverse proxy on Apache (for QNAP)

Question

As I cannot access to ports other than 80 and 443 at work, I would like to make accessible some resources using Apache on my QNAP.

In particular I would like to:

set a Virtual Host (using sub1.domain.com) to connect to a service running on the same host (my QNAP) (http://localhost:58000)
set a Virtual Host (using sub2.domain.com) to connect to another host within the LAN (http://192.168.1.1:78080)
set a Virtual Host (using sub3.domain.com) to connect to an external website (e.g. https://www.google.com)

Beside activating proxy_module and proxy_ssl_module (and changing DNS accordingly), I have thought to use the following line codes on httpd-vhosts-user.conf (for 1. and 2.) and on httpd-ssl-vhosts-user.conf (for 3.):

General sections (FYI):

/etc/config/apache/extra/httpd-vhosts-user.conf

    NameVirtualHost *:80

    <VirtualHost _default_:80>
       DocumentRoot "/share/Web"
    </VirtualHost>

/etc/config/apache/extra/httpd-ssl-vhosts-user.conf

    NameVirtualHost *:443

    <VirtualHost _default_:443>
       DocumentRoot "/share/Web"
    </VirtualHost>

Virtual Host to connect to the service running on http://localhost:58000

<VirtualHost *:80>
   ServerName sub1.domain.com
   DocumentRoot "/share/Web/sub1"

   ProxyPreserveHost On 
   ProxyRequests Off 
   ProxyVia Off 
    ProxyPass /sub1 http://localhost:58000
    ProxyHTMLURLMap http://localhost:58000 /sub1

   <Location /sub1>
      ProxyPassReverse /
      ProxyHTMLInterp On
      ProxyHTMLURLMap  /      /sub1
      RequestHeader    unset  Accept-Encoding
   </Location>

   <Proxy *>
      AddDefaultCharset off
      Order deny,allow
      Deny from all
      Allow from all
   </Proxy>

   <Directory "/share/Web/sub1">
      Options FollowSymLinks MultiViews 
      Order allow,deny 
      Allow from all
   </Directory>   
</VirtualHost>

Virtual Host to connect to other service running on http://192.168.1.1:78080

<VirtualHost *:80>
   ServerName sub2.domain.com
   DocumentRoot "/share/Web/sub2"

   ProxyPreserveHost On 
   ProxyRequests Off 
   ProxyVia Off 
   ProxyPass /sub2 http://192.168.1.1:78080
   ProxyHTMLURLMap http://192.168.1.1:78080 /sub2

   <Location /Asus>
      ProxyPassReverse /
      ProxyHTMLInterp On
      ProxyHTMLURLMap  /      /sub2
      RequestHeader    unset  Accept-Encoding
   </Location>

   <Proxy *>
      AddDefaultCharset off
      Order deny,allow
      Deny from all
      Allow from all
   </Proxy>

   <Directory "/share/Web/sub2">
      Options FollowSymLinks MultiViews 
      Order allow,deny 
      Allow from all
   </Directory>
</VirtualHost>

Virtual Host to connect to the given external site (e.g. google) [credits to kamal @ serverfault.com]

<VirtualHost *:443>
   ServerName sub3.domain.com

   ProxyPreserveHost On

   <Proxy *>
      AddDefaultCharset off
      Order deny,allow
      Deny from all
      Allow from all
   </Proxy>

    ProxyPass /sub3 https://www.google.com/
    ProxyHTMLURLMap https://www.google.com /sub3

   <Location /sub3>
      ProxyPassReverse /
      ProxyHTMLInterp On
      ProxyHTMLURLMap  /      /sub3
      RequestHeader    unset  Accept-Encoding
   </Location>
</VirtualHost>

However none of these Virtual Hosts work (I have a connection fail or endless loading).

Could someone please help me reviewing the code?

Thank you very much in advance!
