I'm new to UTM and struggling to get some basic filtering rules set up. I have no idea at this point if I'm supposed to be using web filtering or firewall rules, or if this is a separate (possible related) DNS issue.
I have several servers on a network behind a UTM9 device that I do not want accessing the internet, with the exception of a few services, such as Windows Update or Crashplan. So far, I have crashplan working, using a firewall rule to allow HTTP/S from said servers to crashplan IPs (and DNS Host records).
I'm trying to do the same for Windows Updates, and struggling miserably. According to the logs, I see lots of :80 and :443 requests, but I have a FW rule allowing all the suggested windows updates DNS hosts from the servers, but still nothing. Most of the dropped packets are trying to reach Amazon and Google, from what I can tell. Upon further research, it seems I should be doing this via Web Filters, but I have no idea how to do this, is this the incorrect application?
Thanks...
