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 am having the same issue on my UTM 9 firmware 9.405-5. I have confirmed my internal DNS IP is listed under Remote Access > Advanced. Users cannot connect to shared drives after they connect to the VPN. I can't ping the server name either. I can ping the server IP address fine and can access map drives by IP but not server name.

    I also have 'VPN Pool (SSL)' under Network Services > DNS > Global > Allowed Networks. I have also tried 'ipconfig /flushdns' and 'net stop dnscache && net start dnscache'.

    Can anyone help?
