UTM DNS not working when connected with SSL VPN

GuidoCraenen

Hello,

I'm connecting from outside my network from a Mac with Viscosity and SSL VPN to a Sophos UTM. On the UTM I'm using the local DNS. That's working ok on the internal network. When I connect with SSL VPN it is not and I have to use ip addresses instead of the dns names. I followed the knowledge articles and gave the IP address of the UTM in the SSL VPN setup, enabled the DNS option with that IP address in Viscosity and added the SSL VPN pool to the allowed networks on the DNS services page, so I'm not sure what I'm missing.

    I do not use this since not all my VPN-workers get access to Internal network. Some only get access to services behind another site-to-site connection and therefore will most likely be not able to reach internal Address. But good to know that Internal Address should also work in most environments.

    Managing several Sophos UTMs and Sophos XGs both at work and at some home locations, dedicated to continuously improve IT-security and feeling well helping others with their IT-security challenges.

    Sometimes I post some useful tips on my blog, see blog.pijnappels.eu/category/sophos/ for Sophos related posts.
