I have CoovaChilli 1.3.1.4 on Raspbian, with the DNS, DHCP and web server running altogether.
I need to resolve a domain named app.mydomain.com. When I start the system with CoovaChilli disabled I can access app.mydomain.com. But when CoovaChilli is enabled, the domain stops from being resolved. Others domains, however, are resolved normally.
So if I ping app.mydomain.com with CoovaChilli enabled I get:
ping: unknown host app.mydomain.com
Looking into /var/log/daemon.log I see the following message:
coova-chilli[803]: dropping dns for anti-dnstunnel (type 6: length 45)
coova-chilli[803]: dropping malformed DNS
Enabled settings on /usr/local/etc/chilli/config are:

Actually I'm using bind9 as DNS service.
Any ideas on how to fix this?
Note: I didn't install Radius yet. I want to get this problem fixed before I decide if I'm going to use Radius for authentication.
It was only a misconfiguration. HS_DNS1 should be 192.168.42.1 and not 127.0.0.1.
Also, I forgot to include app.mydomain.com to the hosts file.
Now it's working.
