I want
to host some websites behind a
VPN and I need some help with the finer points of the configuration. Thus far I've settled on OpenVPN + Bind9 and I want
to configure the domains like this:
External DNS
mail.example.com
www.example.com
vpn.example.com
I want
to be able
to connect
to the
vpn using '
vpn.example.com'. Once connected I then want
to be able
to resolve anything which is '*.
vpn.example.com' with the DNS server sitting behind the
VPN.
I know that OpenVPN can push DNS servers
to clients when they connect. I am having trouble though with the DNS config, both internal and external. I've gone through a few tutorials etc. and tried
to reason about it myself but I'm not getting anywhere.
So my main question would be does the above configuration make sense? If so, any general pointers or examples would be greatly appreciated.
Here's what I've tried so far based on this tutorial (I've redacted my domain with example.com). When I try the tests with dig at the end
to check the resolution is working it fails.
db.
vpn.example.com
$TTL 15m
vpn.example.com. IN SOA ns.
vpn.example.com.
[email protected]. (
2009010910 ;serial
900 ;refresh
900 ;retry
900 ;expire
900 ;minimum TTL
)
vpn.example.com. IN NS ns.
vpn.example.com.
ns IN A 192.168.0.2
test IN A 192.168.0.2
