I do believe that SMG you configure is in mixed mode i.e. control center / scanner.

If that is correct you have to ensure proper communication for SMTP (port 25 / TCP), NTP (port 123/ UDP) and DNS (if external DNS wil lbe used port 53 UTP/TCP). Not included ports need for engunes update (AntiSPAM and AntiVirus).

The Messaging Gateway works just fine with only one IP address and interface.

dear tonev

 

can you please explain with control center and scanner mixed mode means what exactly

 

secondly as mentioned by Davis SMG with 1 interface should work fine with 1 interface for

outbound /inbound

Hello,

Scanner and Control Centers roles are explained very well in SMG documentation.

Scanners process inbound and outbound messages and route messages for delivery.
Scanners download virus definitions, spam signatures, and other security updates from Symantec Security Response. Scanners run filters, render verdicts, and apply actions to messages in accordance with the appropriate policies and settings.

The Control Center is a browser-enabled application that interfaces with the Symantec Messaging Gateway system.

It is posible to have a Control Center and Scanner on a sigle appliance (what I called mixed mode).. 

Regarding number of the interfaces - as per SMG installation guide: "You can configure the Scanner to perform both inbound mail filtering and outbound mail filtering. You can use the same Ethernet interface for both inbound mail filtering and outbound mail filtering"

Yes you can have a combo box with both the control center and scanner roles. It can do inbound and outbound mail on a single IP/interface.

i want to add another default gateway to my smgt

right now setup with 1 eth0 interface .is it possible i configure second eth0 interface and give another ip of default gateway ?

I can not understand the question very well.

Are you tring to configure a virtual nic interface (for example eth0:0) or just trying to configure another net interface (eth1)?.

Could you please clarify?

There is no option to have the 2 NICs use different default gateways.

Can one Scanner NIC be used for mail and the other Scanner NIC to communicate with the Control Center?

Absolutely. This is set under Administration -> Configuration -> Scanner -> SMTP -> Advanced Settings -> Delivery under the bindings settings.
