I'm not sure what you mean with "the firewall," but with the stated
configuration, DGD actually does listen on 3 ports: TCP 2000, TCP 2002,
and UDP 2002.  If "the firewall" did not inform you that UDP 2002 is
open, then you are not seeing a list of open ports.

Assuming that the firewall lists "active" connections instead of ports
listened on, I can think of a possible explanation for port 2868: it
could be a UDP connection to the DNS server opened by DGD.  In that case,
it is probably closed already, since such a connection is closed as soon
as the name server information has been obtained.  Future name server
requests will be on different ports.
