My ASG is configured with static DNS mappings for my home machines. My home domain is, "alistairs.net". This is externally registered with DynDNS using custom DNS, and is valid externally. However, I want internal names to use the internal DNS by using statically-mapped entries on ASG. I've configured a couple of static maps (e.g. "mac-pro.alistairs.net")
If I attempt to resolve these names from an internal machine, DNS will time out. DNS requests for domains *other* than alistairs.net work fine.
Interestingly, if I attempt to resolve my domain using ASG, it can't find an authoritative server:
> set type=ANY
> alistairs.net
Server: 172.16.1.1
Address: 172.16.1.1#53
Non-authoritative answer:
alistairs.net mail exchanger = 5 aspmx.l.google.com.
alistairs.net mail exchanger = 10 alt1.aspmx.l.google.com.
alistairs.net mail exchanger = 15 alt2.aspmx.l.google.com.

I notice that my DNS log file is full of Bonjour errors, followed by "Disabling EDNS":

I restarted the ASG, but DNS for my own domain still doesn't resolve.
I have a couple of statically mapped addresses, and no DNS request routes.
The NSLOOKUP log above was performed from a machine inside the network, using "alistairs.net" as default domain, and ASG as its DNS server.
