I am trying to get several servers enlisted into MAAS. It boots, finds ens1f0 and continues loading stuff. After downloading some packages it tries to connect to http://.maas-internal:5248/MAAS/api/2.0/machines/?op=is_registered… But this fails because it is trying to use the upstream DNS servers configured in MAAS instead of the internal DNS server of MAAS.
Comparing this to the tcpdump, I never see the enlisting image trying to access 10.241.96.21 (MAAS) when querying for http://10.241.96.0--24.maas-internal/
