Default Apache on two servers but one public IP

HI all

I have a problem with a recent new server where I deployed several new sites. The problem is that trying to browse the new sites I can go on and old one and no further.

I have one IP public address 62.123.142.xxx. DNS service is given from domain's mantainer. Through an admin panel I can assign the third level names to each domain and point these to my public IP. Thus when I need a new level I just go there and add a line:

domain1 --> 62.123.142.xxx
www.domain1 --> 62.123.142.xxx
web.domain1 --> 62.123.142.xxx
admin.domain1 --> 62.123.142.xxx

domain2 --> 62.123.142.xxx
www.domain2 --> 62.123.142.xxx
web.domain2 --> 62.123.142.xxx

Each of these is served from a local server (192.168.0.8) and there is no problem with this.

Recently have added one new Web Server 192.168.0.7 with 3 new domains and have added this in the maintainer DNS.

domain3 --> 62.123.142.xxx
www.domain3 --> 62.123.142.xxx
web.domain3 --> 62.123.142.xxx

nslookup seems ok. Each resolves to my public IP.

The problem is that trying to browse the new address www.domain3, or www.domain4 and www.domain5 I see the first one www.domain1.

In apache each is set like this on server 1 :

<VirtualHost 192.168.0.8:80>
User "#1000"
Group "#1001"
ServerName beenzeria.com
ServerAlias beenzeria.com www.beenzeria.com
DocumentRoot /usr/home/beenzeria/public_html
ErrorLog /usr/home/beenzeria/logs/error_log
CustomLog /usr/home/beenzeria/logs/access_log combined
ScriptAlias /cgi-bin/ /usr/home/beenzeria/cgi-bin/
DirectoryIndex index.html index.htm index.php index.php4 index.php5
<Directory /usr/home/beenzeria/public_html>
Options IncludesNOEXEC FollowSymLinks
allow from all
</Directory>
<Directory /usr/home/beenzeria/cgi-bin>
allow from all
</Directory>
UseCanonicalName on
</VirtualHost>

and in this way in server 2:

<VirtualHost 192.168.0.7:80>
User "#1005"
Group "#1005"
ServerName webmail.0email.it
ServerAlias webmail.0email.it webmail2.0email.it
DocumentRoot /usr/home/squirrellmail/public_html
ErrorLog /usr/home/webmail/logs/error_log
CustomLog /usr/home/webmail/logs/access_log combined
ScriptAlias /cgi-bin/ /usr/home/webmail/cgi-bin/
DirectoryIndex index.html index.htm index.php index.php4 index.php5
<Directory /usr/home/webmail/public_html>
AllowOverride None
Options None
Order allow,deny
Allow from all
</Directory>
<Directory /usr/home/webmail/cgi-bin>
allow from all
</Directory>
UseCanonicalName on
</VirtualHost>

in /etc/hosts there are the additions ie:
192.168.0.7 newdomain4 newdomain5 newdomain6

local DNS is only used for cache.

What can I set to have this working?
Tks on advance.
Marco

Default

You have your two servers running at private addresses 192.168.0.8 and 192.168.0.7.
From the outside these are accessible through Network Address Translation from public address 62.123.142.

You have too high expectations from your NAT router

You expect your router, a simple layer 2 device, to be able to parse the HTTP requests and translate the 62.123.142 address to 192.168.0.8 in case for HTTP request for www.beenzeria. If a HTTP requests comes in for webmail.0email.it you expect this to NAT to 192.168.0.7.
Routers are too dumb to be able to do this.

I am afraid you need a second public IP address for your second server
