Robert,

388/UDP does not have to be open for the LDM to work.  Having both
TCP and UDP open will result in the filter indication going away, but
it is not needed for the LDM, which does not use UDP.

OK.

OK.  Things look good now:

% nslookup 68.60.162.3
Server:         128.117.140.62
Address:        128.117.140.62#53
