The "domain" in NFSv4-speak has nothing to do with DNS. It _can_ be you 
DNS-domainname but it can be anything as long as client and server agrees. 
If they disagree you can still mount, but all files will be owned by 
Nobody-User and Nobody-Group if I remember correctly.

Shield up, Scotty! 

Looks like a firewall issue to me. Do you allow incoming traffic to port 

Can you mount over NFSv3?
