If traffic is passing through, then you need to open up the port.  You'll know which 
way you need
to open it if you see blocked connections in your log.  If you don't see them and DNS 
is working
fine, then you're cool.

what forwarding does is if the internal dns cannot answer a dns request then it 
forwards the request
to an external dns and then is supposed to get a return answer it then feeds to the 
internal dns
client. this is done so that all the client machines don't choke your bandwidth with 
dns queries
when the internal dns server doesn't have the answer in its cache. so do I need to 
open port 53 on
the firewall to the internal dns server so that it can get the answer to it's queries 
from the
external dns server? I'm not sure

     if your dns server is answering requests for internal clients only, then you do 
not need to
     create any additional rules or open ports, the default rule already allows this 
outbound dns
     traffic.  if you want your dns to answer external requests, then yes you need to 
allow for it.

     all this assuming the server is behind the firewall (not in the dmz)

          do I need to open the dns port if my internal dns server (configured as a 
dns forwarder)
          is set to use my isp's dns to forward requests it cannot answer?
