Trying to block downloading of file extensions in browsers (.exe .scr etc).
I've followed the guides and manuals I've found online but it just seems to be ineffective. We have 2 Draytek firewall's on different connections - a 2925 and a 3900 and both seem completely ineffective.
They both run entirely different OS (Liux and DrayOS) and both are running latest FW.

Does anyone else have this working on either model?
