Any iptables settings active on the workstation host? Run "iptables -L
-n -v" to see. Blocking UDP/TCP port 53 in FORWARD?

That is correct. The /etc/hosts file has the required localhost IP
mapping line?

If you query a different DNS server than your router, does it change
anything on the workstation?

dig -t ANY 3dsafety.com @dns1.earthlink.net

Or if you explicitly use TCP for queries?

dig +tcp -t ANY 3dsafety.com [@dns1.earthlink.net]

Here the domain resolves proper, although it has a "strange" SOA set:

3dsafety.com.           86400   IN      SOA     localhost.
hostmaster.earthlink.net. 2003082000 86400 900 2592000 86400
--> localhost!?

Do you have same resolution problems with other domains too?
