Firewall/NAT

Hello all.

We use monowall as our main firewall and i am stuck on a certain issue. we currently use it to pass port 443 to one server for our Outlook Web Access and all port 80 to our web server.

I would like to use different headers on my Web server, running iis, to differentiate between websites.

So if an external bod types

www.a.com they are forwarded to the appropriate website on my web server (this is currentl working internally via my internal dns)

What i happening is that the domain name gets resolved and the external ip address is passed as the header so the correct website is never displayed, only the default one.

How do i tell monowall to pass through the original dns header rather than resolving it to the ip address.

Many Thanks in advance

can anyone help or have any ideas?

is this even possible?

Is there a better way of doing it?

swith your DHCP from your m0n0wall to your windows server and set i hand out your local windows DNS address for DNS resolution.  also, your local windows DNS should be configured to use your local private IPs not your public IPs.
