Filtering rules for Packet Filter plugin

Hi everybody,

After installing Packet Filter plugin, I looked different options and I searched on the Internet, I found that we could filter the type of data exchanged and that the Packet Type “IQ” meant “other data”.

So my question is, is it possible to specify this data type and depth of the filtering system? I’d like drop or reject audio or video files, and accept text files or spreadsheets, for example … I thought filter by file extension but anyone can modify it or compress audio and video files. So I thought filter by size, is it possible?

Best regards
