Redirect traffic from one IIS server to another LAN IIS Server

Hi there,

The current setup is this:

Small Business Server 2003 R2 on 192.168.100.0 LAN behind a 10.0.0.0 range
network (DMZ). SBS Server has 2 network cards. One for LAN (192), other
for WAN (10). The 2nd network card (WAN) on the SBS box is connected
directly to ADSL Modem on 10.0.0.0 range. Web traffic on ADSL modem
(10.0.0.1) forwards all port 80 traffic to WAN card (10.0.0.3) to display
SBS websites and SharePoint v2.

I have another server on the LAN (192.168.100.12) which I have installed IIS
Server and SharePoint v3. I am trying to get this SharePoint website on the
internet.

As all WAN traffic is received to the SBS box via the WAN card, I am trying
to figure out a way of the SBS IIS (192.168.100.1) box to redirect to the
SharePoint Server website on the 192.168.100.12 box. I can get this working
fine on the LAN by having http://sharepoint redirect to http://server2k3-2
resolving with internal DNS, but obviously this will not work externally -
when trying externally the URL changes to http://server2k3-2 which internet
DNS will not recognise and fail.

How can I get this working? I can get a website to hit the SBS IIS box
which is then in itself redirected to a directory containing an index.html
page and displays correctly. However SharePoint v3 is a website not file
based only accesibly by http://sharepoint. (or am i wrong?)

How can i get http://sharepoint.mydomain.com to be received by my SBS box
and redirect to my secondary SharePoint v3 LAN box? Is there a better way?

Remember the LAN is separate to the DMZ. It would work if I got rid of the
DMZ and had the ADSL modem on a 192 range with the other computers and
servers because I could port forward to another LAN box directly from the
Modem.

It could also work if I got a second network card which was configured as a
10 range and port forward to that WAN card on the secondary box. However I
do not have another network card at the moment and not keen on getting rid
of the DMZ

Any ideas?

Thanks

Steve

Re: Redirect traffic from one IIS server to another LAN IIS Server

Use ISA server on your SBS box and configure a publishing rule for
SharePoint.
Since the name used for accessing SharePoint from the Internet is different
from the names used for the intranet, make sure you:
- Configure ISA to forward the original host name in the request
- Configure alternate access mapping (AAM) in SharePoint central
administration (tab "operations")

This kind of setup is now well documented on MS site and in various blogs
now.

Re: Redirect traffic from one IIS server to another LAN IIS Server

Hi,

I think you are looking for some kind of reverse proxy implementation (I'm
not 100% sure given the description below).

Something like ISA Server can do this for you.

Cheers
