I did some testing and made this work, but I wanted to verify that my findings were correct.

I have a web server sitting on an internal address. I wanted to use a stateful filter on BM38SP2 to allow external traffic to connect to the web server on port 80. I created a stateful exception with the destination address of the "real world" outside address. I created a second stateful exception with the destination address of the internal address. Outside traffic gets to the server just fine.

I couldn't get it to work with a single stateful exception. Is that correct?
