[WebFooL]

Hi,
Follow my guide to installa and configure a revers proxy in Apache2.

Open terminal or ssh and run:

a2enmod proxy
a2enmod proxy_http

And

a2enmod rewrite

Now edit /etc/apt/sources.list add or uncomment:

deb http://ftp.debian.org/debian lenny main contrib non-free
deb http://security.debian.org lenny/updates main contrib non-free
deb http://volatile.debian.org/debian-volatile lenny/volatile main contrib non-free
deb http://www.backports.org/debian lenny-backports main contrib non-free

Now run:

apt-get update

Then run:

apt-get install libapache2-mod-proxy-html

Now open the /etc/apt/sources.list and comment or delete the sources you added.
Run:

apt-get update

Verify that the untangle server only upgrades agains untangle servers.

Now create the new site file

nano /etc/apache2/sites-available/newsite

In this file Enter:

<VirtualHost *:80>
  ServerName dnsname_to_server_or_ip.com
  ProxyRequests Off
  <Proxy *>
    Order deny,allow
    Allow from all
  </Proxy>
  ProxyPass /subfolder/i !
  ProxyPass /subfolder http://Internalserver_dns_or_ip/
  ProxyPassReverse /subfolder http://Internalserver_dns_or_ip/
</VirtualHost>

*if it is a "https" site use "SSLProxyEngine on"
Now go to:

/etc/apache2/sites-enabled

And run:

a2ensite newsite

Now reload Apache

/etc/init.d/apache2 reload

Lets make sure that the proxy was installd.
Go to:

/etc/apache2/mods-enabled

Run:

a2enmod proxy

&

a2enmod proxy_http

Then restart the apache.

/etc/init.d/apache2 restart

If all workt try accessing http://Untangleip_or_DNS/subfilder

Enjoy.
