One public IP, two webservers

Hi Dan,

URL1 and URL2 are completely different web sites.

Web1 (URL1) will be on Win2003 server. NAT box points to Web1 on port 80. I
can only assign one IP address for port 80.

Web2 (URL2) will be on Win2000 server.

It's definitely not Load Balancing.

It's not redirecting really(?)...

I am hoping that typing URL1 from the internet goes to Web1 server and
typing URL2 goes to Web2 server.

URL1 and URL2 are using the same Public IP

Thanks again for your help,
Aaron

Ok, so URL 1 and URL 2 have to be DNS'd on the front end to the same IP,
which the NAT box will then allow requests in on port 80. Then, you will
need two IP's and a NAT intelligent enough to determine which BE IP gets the
request (by reading the host header - ie the host information in the
request).

Other than that, you could host both sites on the one server, and pull the
content from the other server by using the settings in the home directory
tab, but I cant really see what that gets you.

Sorry - I guess this one is a bit out of my league.

Thanks for your prompt reply to my question Paul

My understanding is that these articles are for multiple websites on a
single server?

What I need to do is redirect to a different Webserver internally from the
first web server.

OK, try this KB article then. I thought you were asking about hosting
two web sites on one IP address, which would require you to use host
headers.

Yes one public IP, but two private IPs (one for each server)

Many kluges are possible, but a second IP address is the best solution
to guarantee it works.

Hello,

IIS can only redirect, not act as a Reverse Proxy.

You can:
1) Add another public IP, and forward it in your NAT to the other box.
2) In the first webserver, redirect to port 81 (for example), and forward
this IP in your NAT to the other server.
For example, say that you have the domains <a style='text-decoration: underline;' href="http://www.yourcompany.com" target="_blank">www.yourcompany.com</a> and
srv2.yourcompany.com
In IIS on Server 1(Web1), you have a hostheader for srv2.yourcompany.com.
This is also a redirection to srv2.yourcompany.com:81 (see link from Paul
Lynch for setting up redirection)
So, whenever someone types <a style='text-decoration: underline;' href="http://srv2.yourcompany.com," target="_blank">http://srv2.yourcompany.com,</a> they will end up on
srv2.yourcompany.com:81, which is a port open in your NAT device, and
forwarded to Web2. Note: You will also be able to access Web2 with
<a style='text-decoration: underline;' href="http://www.yourcompany.com:81" target="_blank">www.yourcompany.com:81</a> because everything uses the same IP.

Yes, this is _ugly_, but it works.

3) Use a product such as <a style='text-decoration: underline;' href="http://www.octagate.com/HTTPRedirect.asp" target="_blank">http://www.octagate.com/HTTPRedirect.asp</a>
4) Use Apache as a Reverse Proxy:

My recommendation would be #1, or #3.

What exactly are you using to front-end and NAT the request? It may be that this hardware device can do Host-Header Translation and forward to the correct server.

If you redirect one server to the other, you are creating another dependency for the site. Web1 has to be running to forward requests to web2. This is a bad practice, at best.

The other option would be to serv the sites on different ports (again it depends on your firewall). You could configure one site as SSL and the other as HTTP. All incoming requests on 80 are forwarded to web1, and all incoming requests on port 443 are forwarded to web2. This is the cleanest solution, if you can make one of the sites SSL.
 >> Stay informed about: One public IP, two webservers 

Hello,

I do want to host two websites on one IP address on a single server. I use host headers as you suggest but both websites point to the same home directory. Is there a way to point <a style='text-decoration: underline;' href="http://www.site-1.com" target="_blank">www.site-1.com</a> to directory /site-1 and <a style='text-decoration: underline;' href="http://www.site-2.com" target="_blank">www.site-2.com</a> to directory /site-2?

Thanks
Minh
