Re: Recursive DNS w/ GCI

I thought that may be the case, however if I configure any local hosts
on my network to use either ACS or GCI directly (and not my local BIND
cache), everything works fine. ACS does not appear to limit DNS to
their own customers. As far as I can tell, it's either the BIND
server itself (however queries to which the server is authoritive work
fine) or something about the RCA modem from GCI.
