multiple servers behind oBSD

[pickle <pickle_(_at_)_sdf_(_dot_)_lonestar_(_dot_)_org>]

Hello all!

Just a question i'd like to ask that im having trouble with.
I have a opennsd 2.7 box that is currently a web server, ftp server
and a mail server, and also serves as a gateway for all the internal
boxes.

Here's the question:

3 of the internal boxes, 2 running oBSD and 1 running linux.  I
want to allow them to be used as active servers.

(internet) <------> openbsd gateway	
		    [gate.domain.com] (2 nic)(internal nic is 192.168.x.1)
                    web, ftp, mail server
                  /              |         \
                 /               |          \
            oBSD box 1      obsd box 2       linux box
        dopy.domain.com   gimp.domain.com    test.domain.com
        web + ftp server   web + ftp server   web + ftp server
          192.168.8.200	    192.168.8.205	192.168.8.210


If someone just types www.domain.com of ftp's into it they will hit
the gateway server.  What i'd like to do is if some one types
gimp.domain.com they will route thru the gateway box and hit obsd server
#2.  same goes to all the boxes.

Currently i have this in my httpd.conf:

<VirtualHost 1.1.1.1> (my ip changed)
	ServerName dopy.domain.com
	ProxyPass / http://192.168.2.200
	ProxyPassReverse / httpd://192.168.8.200
</VirtualHost>

<VirtualHost 1.1.1.1> (my ip changed) 
        ServerName gimp.domain.com
        ProxyPass / http://192.168.2.205
        ProxyPassReverse / httpd://192.168.8.205
</VirtualHost>

<VirtualHost 1.1.1.1> (my ip changed) 
        ServerName test.domain.com
        ProxyPass / http://192.168.2.210
        ProxyPassReverse / httpd://192.168.8.210
</VirtualHost>

I also havein there:
LoadModule proxy_module /usr/lib/apache/modules/libproxy.sl

only thing im unsure about is what to put inthe /etc/ipnat.rules
or anyother conf file to get this setup to work.

Any info will be appreciated!
