Subject: [WhatsUp Forum] SMTP test
fails
Hi Folks.
I am a first time user of this product and
have enjoyed working with it up until this problem that won't go away. I hope
you can help.
I am using What's Up Gold 6.0 and been having
problems getting the WUG server to send SMTP alerts to a Windows 2000
Server/Exchange 2000 Server.
I have followed the FAQ that came with it and
the changes have had no effect on the outcome. It still fails. The WUG server
can send email via Outlook Express, but as that uses POP3, that may not make
much of a difference.
Let me layout the physical connections cause
this may be part of the problem too.
WUG Server (DMZ Zone) (Internet Routable
IP)
|
Firewall ---------> Internet
|
Exchange Server (Internal LAN Zone) (NAT Address to a
specific Internet routable IP)
I have tried using the IP of the server (it's
a 172.16 address) and I have tried using the IP address that is one-to-one
mapped through the firewall to a routable IP address that is also shown in DNS
MX records. Both fail. I was able to use another Exchange server on a totally
different subnet as a forwarder to my exchange server, until a firewall was
put in place at their end.
I was also once able to do this, but not until
I put the WUG server into the same domain as the exchange server. Due to
sharing problems with other departments I've had to move it from my Internal
network to the DMZ and made the server stand alone. I rebuilt it totally when
I did this.
This Exchange/W2K server is running active
directory and is in native mode, but I can pass SMTP traffic through it and
receive from it as well.
I hope this is enough to let you pass on some
ideas to me on where to go next.
