[ale] Conceptual issue with self-hosting

[Trey Sizemore]

Hi all-

I'm having a bit of a conceptual issue I'm trying to fight through.  I
have a domain that I host locally here at home.  I'm assigned a dynamic
IP by my ISP, so I use zoneedit.com and ddclient to update my A records
at zoneedit.

My Internet facing IP gets updated periodically and I have A records
for mydomain.com, www.mydomain.com, and oes.mydomain.com (which all
point to the same IP address).  Zoneedit also has an MX entry I created
to pass mail onto oes.mydomain.com.

I have a firewall at home and a DMZ behind which sit a couple of
boxes.  I have rules in place which pass HTTP packets to Alpha and an
SMTP proxy setup for mail that gets passed to Bravo.  One box (Alpha
with IP 192.168.0.200) is a webserver and pointing to mydomain.com or
www.mydomain.com gives me the index page on Alpha.

The other box (Beta with IP 192.168.0.201) is a mail server.  It also
has the ability to access mail via a web interface by going to
192.168.0.201/mail *internally*.  However, I want to be able to access
the webmail interface *externally* as well, but of course going to
mydomain.com/mail or oes.mydomain.com/mail doesn't work.  I assume that
this is because these requests are going to Alpha and not Beta.

Alpha also acts as the DNS behind the firewall for the machines on the
subnet.  I have entries for both Alpha and Beta there (A and CNAME
records with name and IP).

My question is:  how can I access the webmail interface of Bravo on the
outside given my current setup?

Trey
