Not sure how this is happening to this magnitude, but after turning up Netflow on our edge routers and MSFC, we appear to be creating thousands of connections on our Firewall as our internal DNS server tries to resolve FQDN's externally.
Is there a simple way to turn off DNS resolution for FQDN's in Netflow or NPM? We're running NPM 9.2 and NTA 9.1 SP3.
Thanks,
George
