Question : How do i get OWA to work with Barracuda Spam and Virus Firewall

We just recently installed the Barracuda Spam and Virus Firewall on our network.  To get this to work properly we had to change port forwarding on our firewall to point all incoming mail to the barracuda.  Now our Outlook Web Access (OWA) won't work at all.  What configuration do I need to make to get OWA back up and running again?

The only think that needs to go to the Barracuda is  port 25 traffic, you should still be able to forward port 443 to the internal IP address of your exchange server.
