I received the following request:
pLease make a Firewall Adjustment to ADD the Following DNS Names for each area:
- xx.example.com, yy.example.com, zz.example.com
When looking at the firewall rules, it looked like I could only do IP addresses, and not DNS names. I only looked at the GUI though. Am I able to perform these tasks via DNS name instead of IP with the Cisco ISR 4321?
