Here is what I have:

WAN: x.x.x.244/28 (Goes to a T1 router [firewall off])

On the DMZ interface I have 2 servers using 1:1 NAT:

WEB:  ext: x.x.x.242/32 int:
MAIL:  ext: x.x.x.243/32 int:

First off, why am I unable to ping the external IP from anywhere inside of
On my web server I have a virtual SMTP server I use to send out mail for web
orders.  Whenever I place an order with my webserver without it being behind
m0n0wall, everything works no problem, sends the mail I need it to send.
But whenever I put m0n0wall back in, the mail just goes to my queue and just
sits there, will not send at all.  I also got an error message saying it was
unable to relay when behind m0n0 as well.  I even put in a rule on the WAN
to allow any source to any destination just to rule that out.  I also tried
putting some DNS forwarder records to map "mydomain.com" to the internal IP
of the webserver since I was not able to access the external IPs at all from
inside.   As far as my actual mail server, it seems to be working ok behind
m0n0wall.  As long as I access the mail through the WAN at least (I have not
tried to access from inside yet).  Any ideas?
