How to setup a hosts or lmhosts file on windows SBS 2003

I have a Small Business Server behind a firewall.  The firewall only allows email traffice to and from the Exchange application on the server, however, I'm running in to a problem with a linux webserver on the DMZ side of the firewall being able to get a reply from the windows exchange server.

So, I would like to setup a route on the windows server to allow it an access route to the linux server.  The windows server is NAT'd through the firewall like this:  55.55.55.3 --> 192.168.16.3.  And the Linux server is on the DMZ with a routable IP:  55.55.55.2.

I know a bit more on the Linux side than the windows side, so, Any ideas?

I think this has to be done on the firewall. You say firewall nating...so public to private..and linux on DMZ..is public..on the same router firewall? Your saying linux has no problem accessing exchange but exchange has problem accessing linux? what firewall is it..lynksys?

Hi compinfo,

Plimpias is right.  Your Exchange server (internal) is configured to use your Firewall as it's default gateway.
There are no other routes that you can put on the server to force the firewall how to deal with the traffic.

The route would need to be set up on the firewall.  I know from your other thread (http://www.experts-exchange.com/Networking/Email_Groupware/Exchange_Server/Q_21136720.html) that you're having trouble getting the firewall to route from your DMZ (public) to your LAN (private NAT) network for SMTP.

I still think this is a problem with the Watchguard not handling the SMTP properly.
I suggest that you configure the Linux box to send emails out through your ISPs smarthost - which should work in this environment.
See the other question for details.
