150 TopicsCan BIG-IP DNS recursion only my domain?
Hi We are using F5 DNS as DNS server and have many CNAME record. We want to query those CNAME record and then get IP as a result too. (Which solved by Enable "recursion yes; in named configuration) But we found problem that our F5 DNS perform recursion on EVERY domain client asking. (eg. f5.com, nginx.com., etc.) We want F5 DNS to answer query on only domain we handle (many domain in zonerunner and gslb) How can we do that? Is it possible to do that? because "recursion yes;" is config on named configuration. I think it's global configuration. and "allow-recursion {}" is only check for client IP address (it's not check on domain we handle) Thank you21Views0likes2CommentsSizing for HW and SW based

Hello, What is the recommendation in adding GTM and LTM/AWAF devices in multi datacenter More explanation if we have HQ and DR datacenters HQ data center GTM device (One device) LTM/AWAF Device (Pair) DR data center GTM device (One device) LTM/AWAF Device (Pair) shall we add DR LTM/AWAF to HQ GTM by using DR LTM/AWAF self IP reachable through internet or internally? Please highlight pros and cons for each method Why are we think to add DR LTM/AWAF to HQ GTM is to ensure that HQ GTM will see VS on DR LTM/AWAF down when internet link is down in DR If there another way to ensure that by monitoring links please clarify26Views0likes3CommentsBIG-IQ DNS TPS Per Geo Location
Hi, I recently deployed a BIG-IQ, to manage all my F5 LTM and DNS Tenants, I'm reviewing the information shown on the different dashboards of BIG-IQ. On the DNS Dashboard, there is a section named TPS Per Geo Location. For some reason i'm just seeing the world map, but with no data. Does anyone knows how to enable information on this map? regards,19Views0likes0Commentswhat is the requirement about OS version when adding new gtm/dns to gtm sync group?

Hello F5 experts, Is it possible to somehow logically divide our current F5 DNS F5s so that they have external and internal DNS records without security risks? How it could/couldn't be done, do you have experience with it? Any brainstorming is highly appreciated :) . We have primary BIND servers that delegate a couple of DNS zones to F5s. However, internal services that translate to internal IPs also started to appear, while we want to use GSLB on our 2 data centers, but we clearly do not want these internal IPs to be visible from the Internet. I was thinking about creating a new DNS zone for internal services for which we want to use GSLB and delegate the zone from our primary DNS servers to our F5 DNS, where I would create a new DNS listener (that is, there will be different NS records on primary DNS servers for internal than for external services) on which I would put an ACL only for private IPs. But both the zone and the Wide IPs for internal services will be available on the F5, and I can't create/block it only for a specific listener, as far as I know. Which means that if someone from the Internet directly tries to resolve the internal services and asks the IP addresses of external listeners, F5 will provide them right... At the moment, I have iRule on a Wide IP for the internal services, which only allows private IPs, but I consider this to be only a temporary workaround and we need full solution as internal services will grow.Solved131Views0likes6Commentsirule for DNS traffic

Hi, We have a publicly accessible web hosting server backed by cPanel and currently we are using F5 to handle our DNS. The problem that we are facing is when one of our end customer adds a Zone /DNS record INSIDE his cPanel account and everytime we have to manually check and add those records in F5 to make things work. Is there a solution for this?.655Views0likes4Comments
