How to add a Sonicwall Email Security Appliance in front of an all-in-one exchange 2010 server.

Exchange 2010. I have an all-in-one Exchange server handling all roles. I want to put a Email security appliance in front of it, listening at port 25.

SW Firewall(
Exchange Nat-ted by policy ( port 25  
default receive connectors: client FQDN port 587
                                                 default Exchange port 25

SW Firewall(
SW ES3300 (
Exchange Nat-ted by policy (

-do i remove this default receive connectors and make new one for port 25 pointing to the FQDN
- or do i add just another receive connector ported to 25?

i dont have a test environment to try it out on so i wanted to ask before i make the moves

thank you!

1) you configure the Email Security with an inbound path, pointing to your exchange & leave the exhange intact
2) you reconfigure the NAT policy with the Email Securities IP instead of the Exchange IP

Optionally you can also use the Email Security to scan outbound traffic, inthat case
3) you configure an outbound path on the Email Security with soruce IP the exchange
4) you re-configure, or add one with higher priority, the send connector to use smarthosting and pint to the Email Security

very simple :)
