    DNS Problems


    Dear,
    I'm in trouble in my dns laboratory.
    My environment has three firewalls and gateway.
    One of these firewalls is up dns and gateway receives the service works normally.
    However two of my firewalls and other gateway, which receives as dns provider can not resolve names to external domains, only for domains created within the dns.
    My room was built into the design below:
    Internet <==> GW <==> GW-LAB <==> FW-RI <==> DNS
    Internet <==> GW <==> GW-LAB <==> FW-01 <==> farm.MATRIZ
    Internet <==> GW <==> GW-LAB <==> FW-02 <==> farm.FILIAL
    VLAN:
    VLANs:
    VLAN-GW-FW-01 [GW-LAB, FW-01]
    VLAN-GW-FW-02 [GW-LAB, FW-02]
    VLAN-GW-FW-RI [GW-LAB, FW-RI]
    SERVICES-VLAN [FW-RI, DNS]
    VLAN-MATRIX [FW-01, MATRIX]
    BRANCH-VLAN [FW-01, BRANCH]

    anyone know how to assist me in my problem?

    Do you have DNS forwarders setup?

    I input in file /etc/bind/named.conf.options the option allow-query { any; }
