Exchange 2013 Receive Connector for Applications

I am in the middle of a migration from 2007 to 2013.  They are currently co-existing and I would like to reconfigure all my 3rd party appliacations to send there notifications through the 2013 server.  I have configured a receive connector with the following settings:

CUSTOM - FRONTEND TRANSPORT
PERMISSIONS - ANONOMOUS
REMOTE IP of All 3rd party IP Addresses ( i.e Backup Exec Server, Barracuda SPAM, Barracuda Web Filter, etc)

I have rebooted the server and the Transport service on the Exchange 2013 server as well.

When I send a test message from the barracuda, and/or the backup exec server nothing comes through... I see nothing in the exchange 2013 queue viewer either.....

What am I missing?

Are Exchange 2013 run on both roles in single box?
Try to telnet <custom-frontend tramsport> 25, do you receive a response?
Have you change the SMTP setting of your 3rd application to Exchange 2013?

Hey BSModlin,

You can check the SMTP Receive protocol log. Should identify those IPs hitting your server and any possible rejection codes.

Check this.

How would I create a receive connector on the exchange 2013 server for ALL IP Addresses on the 10.1.10.0 network.....Keeping in mind that the IP of the 2007 Exchange server is 10.1.10.27 and the 2013 Exchange server is 10.1.10.65.

What settings do I need for Authentication, Permissions, and remote network?
