Open Recursive DNS Resolvers
Hello, one of our F5 GTM devices are acting as open recursive dns resolvers. But, actually they should act as to respong for only of our domain queries. I found that this may cause for DDos attacks. Please let me know what are precautions i should take to resolve this.
Thanks, Ravitheja
