Outbound SMTP connection with HAProxy

[Charles Meruwoma]

Hi Everyone,



Please I need help. I have this setup and I want to be able to route SMTP
traffic from the client access servers to the internet via HAProxy:



HAProxy:

Management IP: 10.0.0.133

Virtual IP: 10.0.0.101 [A Public IP address is NAT'ed to this VIP]



Microsoft Exchange 2013:

CAS-01: 10.0.0.169 [Client Access Server]

CAS-02: 10.0.0.170 [Client Access Server]

MBX-01: 10.0.0.171 [Mailbox Server]

MBX-02: 10.0.0.172 [Mailbox Server]







With the above design, how do I setup HAProxy to route external SMTP traffic
from the Client Access Servers to the internet?

Hi,

You don't need any component to route outbound connection. This
is the role of your NAT router.

Each of your CAS simply establish a conection to internet throught
your NAT router.
