You should check that the configuration directory and named.conf file path of your bind installation match the bind config settings in ispconfig.
and if you want to test your local dns server, use this command:
dig @localhost arenahosting.org
Dont use @ns1.arenahosting.org as the nameserver domain then is a subdomain of the domain that you query, so you have to add glue records and a failure does not indicate if it is a problem with your dns server or if you have not setup the gluue records at the domain registry correctly.
