Ok, let me try to put this together. I have one pfsense box with one dynamic IP address, and on another location (other country) I'm running VPS with my DNS server (bind9).
So now, I want to make that dynamic IP from the pfsense box is updated whenever is renewed. Updated where? In my DNS server:
Suppose I have something like this:
pfsense.mydomain.bla. IN A -my dynamic IP-
I never did this, so I don't have much experience with this kind of configuration and I know that I can use free dynamic dns service, but I want to try with my own DNS server.
RFC2136solution for me or something else?
