Not sure if this has been mentioned before, but the Netflow 7 beta has some problems when you access it remotely by the web.
Everything works fine when you access the web interface locally, but when you access it from a remote address you'll see html/javascript errors when accessing some tabs. you also notice a different title, when accessing it remotely it says Netflow Analyzer 6 in the title bar of IE. Locally it says Netflow Analyzer 7.
Somehow you'll get a different interface for accessing remote and local.
By local i ment accessing it from the server it runs on, the url used is then localhost. Remotely i ment accessing it from a pc at home for instance by the public ip.
Hope this makes some sense.
The tabs i mentioned can be found by clicking on a ip group and then select application, source, destination tabs, all except the first one (traffic) give HTML errors.
