BIGIP DNS forwarder

Anyone ??

Hello,

Thanks for the reply cjunior.

But what dns listner has to do with this, also can I delegate the zone to external bind for which as per the zonerunner my F5 dns is the authorotative server. All I want is to forward all dns traffic from f5 to external bind server if the A record is not configured on F5.

As I have mentioned in the previous post that we have GSS doing the same thing and passing *.test.com to bind server.

Sorry for my ignorance on this topic as by no means I am expert on this.

Any help with the example will be appreciated.

Thanks, Pankaj

No problem, I asked because the listener can drop "Unhandled Query Actions" and disable "Use BIND Server on BIG-IP."

Hi,

You can configure your external BIND server with F5 DNS Express. So then you can take full advantage of the BIG-IP platform and maintain your BIND environment. Don't forget to set your DNS profile properly.

Please take a look at the following great articles to understand how DNS Express can help you:

Good day, This question seems to be coming up alot lately. I tried this on my DNS system and it worked for me. Can you give this a try?

1. Log into Gui
2. Select the zone "abc.com."
3. Select 'Resource Records'
4. Click the 'Create' button to add the glue 'A' RR for the delegation server.
5. Adjust the 'Record Configuration' values

    a. 'Name' should be set to the name of the DNS server authoritative for test123.abc.com

        NOTE: This should be the FQDN of the host

        ex. ns1.test123.abc.com.

    b. 'TTL' should be set to a reasonable value, say '500'
    c. Set 'Type' to 'A'
    d. Set 'IP Address' to the remove DNS server
    e. Click 'Finished' button

6. Click the 'Create' button to add the 'NS' RR for the delegation server.
7. Adjust the 'Record Configuration' values

    a. 'Name' should be set to the name of the delegated domain, "test123.abc.com."

        NOTE: Make sure this is the domain, not the host

    b. 'TTL' should be set to a reasonable value, say '500'
    c. Set 'Type' to 'NS'
    d. Set 'Nameserver' to the name used in step 7 above.

        ex. ns1.test123.abc.com.

    e. Click 'Finished' button

8. Query the GTM listener for a resource record known only by the delegated DNS server, say test1.test123.abc.com.

9. Enable recursion if you want the local BIND server to do all the work.  Disable recursion if you want the local BIND to only return the referral.

Hope you find this helpful.

recursion yes; forwarders { 8.8.8.8; };
