What type of issues are you running into? Depending on your network config, you should be able to enable syslog logging on the barracuda device and point it directly to the Splunk server, and on the Splunk server make sure you've enabled a UDP data input for port 514 (default syslog port).
That got it... I was setting it up incorrectly. Thank you for the help as I just got Splunk yesterday and have never worked with it before.
Glad to hear it's working, if you need any help with field extractions, etc... let me know. I've worked with various Barracuda devices before.
