Multiple domain names on one IP address

targettl · 12-19-2009, 09:45 PM

Is it possible to have one static IP address with a NAT network forwarding each domain name to certain internal/DMZ IP addresses?
I know you can do it by port but if both websites are on port 80 can you forward to the corresponding server on the dmz.

I ask this because I noticed the website braemere.com.au had to be typed into a web browser and entering the IP which is 202.47.5.7 did not take me to the website.

Yes. What you want to look at is setting up named virutalhosts.

But how can you set-up the gateway to forward the external packets to the right internal IP

I think I am a little lost. Are you saying that you have a single static IP address and want it so that if two different domains point to that static IP the correct webpage will display?

If that is what you are asking then yes you can do that using apache virtualhosts. It will listen on a single IP address and give the correct page by using the domain name as the lookup.

However If you are trying to host a website on two computers internally I am afraid that is beyond me as I don't have any experience doing that.

Code:

you can have as following
Public 202.100.100.100 openport 80 fwd to (A Server)
(A Server) Internal 192.168.1.10 openport 80
(B server) Internal 192.168.1.100 openport 80

where is now apache rewrite code come into the picture
which is need to be configured inside (A Server )

this is the sample in (A Server )

Code:

<VirtualHost *:80>
        ServerName b.server.com.au
        RewriteEngine     On
        RewriteRule       ^(.*)$        http://b.server.com.au/$1 [P]
        UseCanonicalName On
        RewriteRule ^(.*)$ [L]
</VirtualHost>

...............................................
.
# note:-
# /etc/hosts must have this line "192.168.1.100 b.server.com.au" LAN Server
# which is http://b.server.com.au is located on the server 192.168.1.100

last setup all domain to point to your public ip address

you can have many more internal server all open with same port and can be access from external with diffrent domain if you this rewritecode
