My Sophos UTM (home edition) is set to filter and scan all https traffic. I set this up because of my kids using google (which uses https). This causes problems from time to time. With the latest version of the UTM I changed the settings to just scan the following categories. For most things this works fine.
Now I came across a new problem using Flickr on my webpages (hosted external). It seems that a lot of flickr content is blocked. I have added https://flickr.com to the allowed pages within webfiltering.
Looking at the webfiltering log file I get for example the following.
2015:04:30-20:21:40 xy httpproxy[20924]: id="0002" severity="info" sys="SecureWeb" sub="http" name="web request blocked" action="block" method="CONNECT" srcip="xy" dstip="72.30.198.116" user="" ad_domain="" statuscode="502" cached="0" profile="REF_DefaultHTTPProfile (Default Web Filter Profile)" filteraction="REF_DefaultHTTPCFFAction (Default content filter action)" size="3963" request="0xe13fc000" url="farm8.staticflickr.com/" referer="" error="Failed to verify server certificate" authtime="0" dnstime="64779" cattime="44194" avscantime="0" fullreqtime="785283" device="0" auth="0" ua="" exceptions="" country="United States" category="179" reputation="unverified" categoryname="Media Sharing"
2015:04:30-20:21:40 xy httpproxy[20924]: id="0003" severity="info" sys="SecureWeb" sub="http" request="0xe3db5800" function="connect_server" file="dns.c" line="1190" message="connect() on AF 10 socket to 2a00:1450:4002:809::200d failed: Network is unreachable"
I would really like to keep the filtering and scanning in place, not just the URL filtering. Can you give me a hint, How I can fix that?
Thanks
Roger
