F5 AFM (13.1.1) Using FQDN in rules
I've configured an AFM rule to use FQDN in the destination address field, this works well in my lab environment but fails on the customer site. Both F5s are configured with the same setting to allow this feature to work , e.g. Network ›› DNS Resolvers : DNS Resolver List Security ›› Options : Network Firewall - FQDN Resolver
all DNS resolution on the BigIP cli works, can anyone tell me how I can test or troubleshoot the DNS resolver feature for AFM ?
Thanks for the information, I actullay got a fix from F5 support. As follows;
1- Navigate to 'Network ›› DNS Resolvers : DNS Resolver List' and click on your DNS resolver 'dns-resolver'
2- Under Forward zones, click 'Add' and for the 'Name' Enter the dot sign (.), for the address add one of your above DNS servers addresses.
