Configuração do BIND9 para registro.br e internet

[JBREDARIOL]

Bom dia. Estou com dificuldades em configurar o bind9. No momento, somente a propria maquina acessa o dominio www.dominio.com.br e dominio.com.br. As demais maquinas da rede aparecem erro. Possuo 2 IP´s um interno (192.168.0.253) e um externo fixo 186.215.X.X. Abaixo seguem os arquivos :

Já verificou os logs do sistema? Todos (ou quase todos) os problemas do bind podem ser solucionados consultando o log.

sudo service bind9 restart
grep bind /var/log/syslog | tail -20

loading from master file /etc/bind/meudominio.local failed: CNAME and other data

Como eu dizia, está sempre lá nos logs.

www                     IN      CNAME   meudominio.com.br.
www                     IN      A       192.168.0.253

Vc definiu ao mesmo tempo o registro "www" como um "CNAME" e um "A". Ou um, ou outro.
