    If you don't have DNS then your clients cannot resolve to other location on hostname.
    The only thing you can do is to add the clients from the other location in the HOSTS file of all the clients that need to access them but this is not an environment that is manageable easily because it has to be modified on all the clients separately with every change.

    You could also manually add the clients to the UTM and use the UTM as DHCP-server, but I think it doesn't support dynamic updating so you would have to manually manage these entries.

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