Dear Friends, I created um DNS server for network Internal and External same SERVER, but the control by ACLs in named.conf don't work, when I active ACLs the server don't resoluction external domain names. Please, check NAMED.CONF file. // // named.conf for Red Hat caching-nameserver // options { directory "/var/named/"; dump-file "/var/named/data/cache_dump.db"; statistics-file "/var/named/data/named_stats.txt"; /* * If there is a firewall between you and nameservers you want * to talk to, you might need to uncomment the query-source * directive below.
