ESET file was blocked

Question

Hi, 
 I found UTM9 block NOD32 to download a "XXXX.dll.nup" file. 
 Because of it, I added following settings. 
 A) At Web Filter Profiles | Filter Actions | Warned file extensions , I added "nup". 
 B) At Filtering Options , I added a new Exception List:

1) ^https?://([A-Za-z0-9.-]*\.)?eset\.com 
 2) click all skip checks

Unfortunately , the file still not download from NOD32. 
 Who can give any help for me? 
 Thanks a lot!

 Some web servers have a problem with the slight delay caused by antivirus. First, try an Exception for Antivirus for 91.228.166.88. If that doesn't work, you'll need to skip the Proxy for it. This is done differently when using Standard mode instead of Transparent.

In Transparent Mode, this is done in WebAdmin. On the 'Misc' tab of 'Web Protection >> Filtering Options', add a Host definition for 91.228.166.88 to 'Skip Transparent Mode Destination Hosts/Nets'.

DKKDG, the Range definition in UTM is very inefficient because of how the configuration daemon translates the definition into the code that runs the UTM. I don't know the details, but that was mentioned to me at some point in time by one of the developers not long after Range objects were added to WebAdmin. 
 In this case, the CIDR range, 91.228.165.0/24, used in a standard Network definition is the preferred solution.
