Hi,
I have a trileg DMZ with private ip. Ihave a web server that has to communicate with a external SMTP server. When setting upp access rule SMTP from DMZ(Webserver) to External(MailServer), i see that the connection is initiated but after a while i will get 0xC0040038 FWX_E_TCP_NO_SERVER_REPLY. If i try connecting from the firewall i can connect to the mailserver and send the mail.
RSS is disabled.
What am i missing?

(SMTP)Port 25 (Outbound)(No filter)
From Webserver Adress(Private DMZ) 192.168.1.2
To External Ip of mailserver.
All users
Have tried AllProtocols from DMZ to External, doesnt help.
Is there a routing problem on return?(How would i find that)

Hi,
did you published your SMTP server using a server publishing rule?

While sitting at the Web Server,...
Open a commend prompt
Type: "Telnet <mail server IP#> 25" [Enter]
What happens?
What do the ISA Log Monitor say?

The isa log monitor
Initiating connection, (My rule to allowaccess), 0x0 Error_Success
1 minute and 10 seconds later
Closed Connection (My rule to allowaccess), 0xc0040038 FWX_E_TCP_NO_SERVER_REPLY
In additional information i se 152 bytes sent and 0 bytes received.
I know the login works the strange thing is im not getting any response!
Do you want me to run Telnet?
Regards

Hi,
can you ping the destination address? It seems a routing problem.

Should Perimiter access to External be NAT instead of Route?

Hi,
that´s for sure! Because you´re using private addres in the perimeter network.
Your network rules should be like this: perimeter -> NAT -> External

You can not ping anything if you didn't create a Rule to allow Ping. Ping is not automatically allowed,...it is automatically denied unless you setup Rules to allow it.
Forget ping
Test with Telnet.
