I am using Debian on a VPS with static IP and my home network behind PPP with dynamic IP. My pfSense router/firewall shall update my host
home.mydomain.tld via RFC2136 style updates.
After lots of reading through different tutorials I still have no clue how to setup this up correctly. There are some hosts in my zone file and I want to allow updates with a secret key for only 1 host.
Debian automatically creates the file
/etc/bind/rndc.key. I'd like to use a 2nd key and keep this key for local updates which my change all zones.
How to configure BIND to allow this?
