  • Hi,

     

    Could you post steps you performed when configuring DNS Express? Your description is a bit to generic. If I can recall you need at least (assuming you would like DNS express to transfer cone from some internal DNS server) - it could be a little bit different in 11.6, I am using 11.2 right now - but general idea should work:

     

    • Create zone in Local Traffic ›› DNS Express Zones : DNS Express Zone List, if I am not wrong zone name should be the same as domain you want to transfer. In Target IP Address enter ip of source dns server
    • Create new DNS profile and set DNS Express to enable and Use BIND Server on BIG-IP to disable
    • Create VS for receiving zone transfers - in my case it's standard type (probably performance L4 would be better) with port 53, protocol UDP, IP equal to floating self IP on the VLAN via which DNS source can be reached, use DNS profile mentioned above.
    • On source DNS server you have to allow zone transfer for above IP (I think I as well allowed self IP on both devices in HA pair - if you are using HA of course), set send notify to the same addresses - probably only floating will work but I can't check it right now.
    • Then of course set listener vs for servicing client requests, so two VS, one UDP, second TCP on port 53 again with your DNS profile assigned (not sure if necessary, but can't test it right now).

    Above is working for me.

  • Thank you so much for reply My step configuration DNS Express Create Zone in Zonerunner > a.com, Record list is test1.a.com, test2.a.com Create Nameservers > Delivery > Nameservers > Nameserver List > I create a.com 127.0.0.1 My DNS profile enable DNS Express Create Zones > Zones > Zones List > a.com // Status is Successful IXFR.

     

    I try to test query dns test1.a.com, test2.a.com it's work but when i create new record list in zone is test3.a.com i cannot query new record

     

    Do you have recommend to me.

     

  • Hmm, seems that you have GTM enabled, steps I described are for LTM DNS Express module, do not have a lot of experience with GTM so can't really help here.
