That's a function of the DNS servers themselves.</P> <P>Either or both DNS servers can hit an outbound NAT rule on a firewall to translate them to to a public IP there - either the interface address or a reserved other public IP that you control.</P> Tue, 08 Oct 2024 15:22:01 GMT https://community.cisco.com/t5/network-security/multi-nat-with-pools/m-p/5205247#M1116366 Marvin Rhoads 2024-10-08T15:22:01Z
