RED 15 - Web browsing to internal hosts not working

StefanHeymans

Hi,

I've been searching for weeks, tried a lot of GIYF and RTFM without success, so I hope someone can help me with this one...


We have set up 2 RED15's and everything is working except web browsing to internal hosts f.e. http://intranet or https://appserver1

I get following Sophos UTM error in browser:


When I use the FQDN in the browser (f.e. https://intranet.mydomain.local) there is no problem.
This is the same for all hostnames.

All other tests are working with hostname only: SMB, internet, ping (automatically forms the FQDN), nslookup (both hostname and IP address), etc...

Everything looks fine on our AD DNS servers (both forward and reverse).


I configured the RED in Standard/Unified mode as described on: https://community.sophos.com/kb/en-us/116573

I also tried with the Deployment Helper (and changed the DNS addresses afterwards, because it points to the RED itself)

These are the configurations:

This problem exists on all our workstations connected to RED, on all browsers...

    Looks like we found it:

    Web Protection > Filtering Options > Misc > Search domain

    We filled in the domain suffix and now everything seems to work.

    This should be mentioned in the manual IMO...

    Thanks, Stefan, I'd completely forgotten about that!

    Cheers - Bob

    Site-to-site IPsec VPN Astaro Sophos UTM 9

     

    I know this is a very late reply however, I'm adding a note to this for the google foo people. I have been pulling my hair out for the past 4 days looking for a solution to this. My issue was a site 2 site Ipsec vpn that couldn't resolve host names via web browser unless the FQDN was appended. I've tried all kinds of fixes and read hundreds of threads. 

    To resolve my issue on a Sophos UTM 9, it's Web Protection > Filtering Options > Misc tab.
