[afnog] Configure router for smtp

[Okalany Daniel]

Have you configured the static NAT for port 25?

If yes, to confirm that it works,

telnet 41.204.x.y 25

from an external connection.

Subject: [afnog] Configure router for smtp

 

Dear all,

I have a setup like this internal mail server > gateway router > external dns

my internal server is 10.10.X.Y/24
my gateway is 10.10.X.Z/24 and 41.204.X.Y

I have configured my mx records to point to my gateway router.
I have also configured my gateway router with a static nat to point to my internal mail server
But do not recieve my mails.

Is there something i'm not doing right

The configuration is as below.
*****************************************************
interface FastEthernet0/0
 description ***ISP LINK ***
 ip address 41.204.x.y/30
 ip nat outside
!
interface FastEthernet0/1
 description *** Internal LAN ***
 ip address 10.10.x.z/24
 ip nat inside
! 
ip nat inside source static tcp 10.10.x.y 25 41.204.x.y 25 extendable
*******************************************************
I'm using Ms Exchange 2007 as internal mail server

Could any one help?

Best regards,

Benjamin
