How to mark connections and packets for Dropbox windows client?

Hi Guys,

Can any genius on this forum help me mark connections and packets for the dropbox windows client.

I have used torch to identify dropbox traffic, but it appears to go out on many MANY different ports. I assume they are fairly random. I also assume they use a lot of different IP addresses.

Could we make a L7 regex filter to capture dropbox traffic?

Can anyone here help with this? I would be super grateful!

Thanks in advance captain!

Or can anyone suggest any ideas as to how i could go about this?
