Give primary DNS suffix fix the warning ID 414. However,
when using Dig tool from geektools.com, the name server
only repond once. After that, Dig tool always say
connection time out and can not get any response from name
server. Name server is behind Cisco ADSL router, port 53
has been enabled and point to name server. I have checked
ISP and they did not block port 53 on their side. Is there
any workaround to fix it?
 
Currently I only open TCP port 53 on the ADSL router for
name server. Do I have to open UDP port 53?

UDP port 53 is more critical that TCP 53, the default port for DNS is UDP
53.
