f5 GTM as DNS Express and Caching server
Hello.
Our costumerwould like to use f5 GTM as DNS Express server for their own zones. Because they are small ISP they would also like to implemtent f5 as cache server and doing recursive lookups. This meens that this would be an open resolver which is not good. Is there a way (maybe with irule) to limit which source IP addresses can query cache part of f5 GMT, so that we would be able to limit recursive querys only for their clients. I cannot find anything in config, f5 is licensed GTM only.
