Email Gateway External IP

L3 Networker

Good afternoon, currently for sending and receiving mails with Office 365 is using a Cisco CES ( Cisco Email Security ).

 

This device only has a couple of public IPs, it is external to the organization.

 

In Palo Alto, when configuring the SMTP Gateway. Is it possible to set a Public IP? The CES should allow the IP of the Palo Alto (MGT Interface Email services), in this case the Public IP of the untrust interface that the MGT goes out to the Internet, to be allowed and to be able to use them for the notifications by mail.

 

I am waiting for your appreciated comments, thank you in advance for your great help and support.

@Metgatz,

Where the gateway resides doesn't matter to the firewall as long as it can communicate to it and the traffic is allowed, so this configuration would work perfectly fine.
