Publising a Barracuda Spam appliance thru ISA2k4

[mofusjtf]

I am having trouble publishing my Barracuda Spam appliance through my ISA2k4 server. If I use the server publishing rule for SMTP server inbound mail does not work. If I use the same publishing rule and point it directly to my Exchange 2k3 server mail works fine. Is there something I am missing in ISA or is the issue on the Barracuda?

We have a Baraccuda spam filter and I just manually set up a firewall rule to tell all incoming mail to go to the Baraccudas ip address

I tried that but it didn't work.

Does the incoming mail show up on the spam guards logs??

As I was wondering if the mail is getting to the spamguard but not leaving the spamguard

No, it doesn't appear to show up in SPAM gaurd. I'm going to move the Barracuda to the DMZ and then just publish Exchange through ISA as normal since I know that works.
