add a domain to zone

[Pol Hallen]

Hi folks :-)

I've a vpn network on 10.10.10.0/24 and BIND on 192.168.1/24.
I'd like add to my zone a domain as:

myvpn1.org.     A 10.10.10.1

to my zone file.

10.10.10.1 is a vpn client connected to my server (I can ping it).

What's the correct way to add a remote domain to BIND?

Thanks for help!
