Hello @preston, I enabled the option last Friday and boy, did I get results.... My mailbox was flooded with about 30.000 mails.... The majority of them about ActiveSync. We have an on-premise Exchange server and an bunch of connected smart phones. Turns out they all exchange small files with the Exchange server - about 5…

Hmm, still not clear? It doesn't outline the exact route of a packet. I assumed it would first check Access Rules and then, if passed, drop into the Security Services. Diagram doesn't show....

Bummer. Adding windowsupdate.com as exception didn't work. Now I'm stuck....

Let me get this straight - this means I have to create TWO address objects in case I use a wildcard? Like if I create an address object *.microsoft.com, I also have to create www.microsoft.com?

OK, I pretty much know what's going on. As I already suspected - most blocked downloads for multi-compressed ZIP-files are coming from windowsupdate.com. As said, most of the IP-addresses don't resolve. Nirsoft IPNetInfo to the rescue. It lists to who those addresses belong. In this case Akamai and Level 3 Parent. That's a…

Ah, yes, DPI-SSL.... Another thing I'm wrestling with. As soon as I enable it, I'm flooded with users no longer able to access particular websites and the like. And when excluding those sites from DPI-SSL, they still experience problems.....

Well, that's the problem. The blocked downloads are not initiated by a user but by the system. So I suspect Windows (or another program) tries to download updates or something like that. The source IP's don't resolve, which either means it' a rogue source or, more probable, a CDN. But without a confirmed source nor a…

My experience is the opposite? We had a TZ400 and bought a TZ470W. The old one ran 6.5 and the new one version 7. Exported the configuration from the TZ400 and imported it into the TZ470W without any issue....

I have the exact same question: Gateway Anti-Virus Alert: Multi-compressed ZIP/GZIP file blocked — SonicWall Community I switched on "Log virus URI" but alas, without result. Surely there must be a way to figure out what files are tried to download? Simon
-
Right, I had a look at the System Logs, but it doesn't list the URI: Simon

Ok, I switched it on, but where are those virus-uri's logged? Simon

@TKWITS : thanks! You had it nailed with the DNS servers. I had the VPN connection locked down to only allow HTTPS and only connect to the Exchange server. Added another rule to allow access to a local DNS server and now things work as they should. What's a bit awkward about DNS servers in the SSLVPN config; if you click…
