DNS resolution with two pfsense firewall



  • Hi

    I have two pfsense firewall which are connected through an ip address.
    Please refer the below attached diagram for details.

    I am using Bind DNS configured in both firewalls.
    I am able to resolve win-pc.dsekar.internal and laptop.dsekar.internal from ubuntu.dseknat.internal.
    But not able to resolve ubuntu.dseknat.internal from either from the ubuntu.dseknat.internal or from other machines (win-pc.dsekar.internal or laptop.dsekar.internal).

    I have configured the dns forwarders to correct values.

    Please help.

    "I am using Bind DNS configured in both firewalls."

    So which is the SOA for dsekar.internal?

    "I have configured the dns forwarders to correct values."

    Where and what does that mean exactly..  So what does ubuntu use for dns?  Bind running on pf2?  Is this bind authoritative for dsekar.internal - is he secondary to soa on pf1?  Are you creating the records?  Wanting dhcp to do it?  etc..
