Hi, Bert, Hi All
 
I finished the reading of you Linux Advanced Routing  & Traffic Control
HOWTO... Congratulations for the excelent job ! You HOWTO helped me to
implement my firewall and NAT/Routing. 
 
Could you please help me in a little doubt that I can't figure ?
 
I have just one C IP: 200.189.73.130
 
This IP answers for two hosts:  <http://www.realad.com.br/>
www.realad.com.br and  <http://www.realmedia.com.br/>
www.realmedia.com.br
 
In the begining, there was a Windows 2000 machine answering for these
hosts. Today I have ( finaly ) a Linux RH 7.3 Box :)
 
The problem is: I can't use Apache in the Linux box as web server
because of some .asp applications we have here. So, I did a routing from
the linux box to the Windows 2000 box, answering for my internal B IP's:
192.168.0.1 is the linux box.  <http://www.realad.com.br/>
www.realad.com.br has 192.168.0.2 as IP in IIS and
<http://www.realmedia.com.br/> www.realmedia.com.br has 192.168.0.5 as
ip in IIS. 
 
I did the following to route packages that comes from internet to port
80 in the Linux box to port 80 in the internal W2K box:
 
iptables -t nat -A PREROUTING -p tcp -i eth0 --dport 80 -j DNAT
--to-destination 192.168.0.2:80
 
and, for internal routing: 
 
iptables -t nat -A PREROUTING -p tcp -d 200.189.73.130 --dport 80 -j
DNAT --to 192.168.0.2:80
 
 <http://www.realad.com.br/> www.realad.com.br and
<http://www.realmedia.com.br/> www.realmedia.com.br have different
contents. My problem is... How I can route packages that come to
<http://www.realad.com.br/> www.realad.com.br to 192.168.0.2 and
<http://www.realmedia.com.br/> www.realmedia.com.br to 192.168.0.5. Just
remembering, 192.168.0.2 and 192.168.0.5 are IP from the same IIS
machine.
 
 
Can anybody help me ???
 
Thanks a lot
