Thank you, Yuan. Yes, I know about the name mismatch on eth1. I just didn't
get around to fixing that.
And your configuration would work, but it has public and private reversed.
As I said - I'll simply have the DNS server listen on my eth1 interface as
well; that should take care of my issues, although it feels like a hack.
Thanks for all your help!
