I am currently using the Authoritative DNS feature on the Link Balancer and I have captured an hour of DNS traffic using tcpdump in the Troubleshooting section. I would like to use Wireshark to show me only the number of DNS queries it has received and wondered if anyone had a filter to do this. I will be replacing the Link Balancer with a NG Firewall and it does not have the Authoritative DNS feature so will be moving to a cloud DNS somewhere. All of these services charge for the number of queries per month and I am trying to get an idea of how much is currently happening.
I already asked Barracuda to help but could not get Wireshark filter help.
Thank you for any assistance.
