DNS Forwarder cfg



  • hello,
    i want to have the DNS forwarder configured in the following way:
    all the packets from outside going through my pfsense dns forwarder, to forward them to an inner DNS
    all the packets from inside the network to be forwarded to an outer DNS(and if possible to the inner DNS server as well).
    Is this configuration possible or the idea is wrong?
    i do appreciate ur help
    10x in advance



  • From inside to out is possible, it's how the DNS forwarder works. From outside to in isn't possible, you'll have to use NAT for that.



  • ok, but how should resolve than the requests from outside to the inside hosts. I will have soom a server running 2003 in my DMZ serving as DNS. somehow the requests should go through it. any idea? 10x



  • the dns forwarder is just for your LAN PCs. If you want to set up an another DNS server and have it resolve requests from outside then just use  NAT for that.

    Its been a while, so I'm guessing this is resolved.
    I'm not sure about your specific setup, by typically I've seen 2 DNS servers. One for internal resolution and one for external. Personally, I let my registrar host my external stuff, but I dont have a lot going on. If you are going to host your external DNS using W2k3 in the DMZ, then its fairly simple. Put that box in the DMZ, forward UDP and TCP ports 53 through the NAT. Then configure the DNS with the external names and IPs…
    You'll have to notify your registrar of the static IP that you are natting to that DNS server as well.
