Redirect of DNS requests

Redirect of DNS requests

[Trevor Morrison]

Hi,
I have looked back through the archives and searched on "Redirect" but I 
did not find the answer to my specific problem.

I have a RH 9.0 with a 2.4.20 kernel.  The box is running iptables-1.2.7 
and does NAT from my 192.168.1.x network to my  ISP assigned dhcp IP. 
 What I would like to do is redirect a certain domain's email, DNS, or 
Web traffic to a w2k server that sits in my private network, sort of 
like a DMZ situation and have the another domain's services continue to 
be routed to the RH box.  On the RH box I am running Bind and Sendmail 
amoung other things.

 I am sorry if this quesiton has been asked before, but I have looked 
through the last 12 months of the archeives looking for the answer.

TIA

Trevor

You cannot do this using iptables. Iptables does not support the kind of
application protocol filtering you need. 
You can only configure your Linux applications (bind/sendmail/apache) to
do this.
