VMware UAGs and .local DNS unicast resolution

Last week we had our monthly internal security audit where we found that we should update our internal UAG appliances. During the review of our internal system, we also decided to upgrade the fronting UAG. Unfortunately, IT tasks are mostly not as simple as moving just one match to correct the equation:

However, for you it will be, because we will show you how:

Step 1: log into your UAG appliance via ssh as root and the password you have configured during deployment.

Step 2: edit the file /etc/systemd/resolved.conf, eg: vim /etc/systemd/resolved.conf

Step 3: uncomment the entry Domains by removing the # the beginning of the line and set the Domains= to your domain name.

Step 4: set MulticastDNS to no.

Step 5: save the file and exit the editor.

Step 6: reboot the UAG, like switching the one match, and happy DNS resolving ;).

This is a screenshot of my working configuration.

ps: the solution to the match question is…

pps: more riddles and their solutions to come – stay tuned.
