Cisco ASA with Firepower Services, Setup GuideLet’s come to the fourth part: How to Use Umbrella DNS?

Using Umbrella DNS

As the administrator of Cisco ASA, you are able to connect to the free and fast Cisco Umbrella global network DNS service which offers you visibility into all Internet traffic originating from your ASA, and result in a faster Internet experience for your users. If you then want to add an additional layer of DNS security to your ASA, the easy-to-establish connection to Umbrella enables you to access our free trial̶which you can setup (by yourself) in less than five minutes.

1. Setting Up Umbrella

Launch the Cisco ASDM and configure internal DNS servers to use Umbrella as their DNS forwarders.

Step1. Launch ASDM and Click [Configuration].MEMO: If you are using a DNS forwarder as the primary DNS server for your network, update the server to use the Umbrella IP addresses of 208.67.222.222 and 208.67.220.220. If you’re not certain whether you have a DNS forwarder on your ASA or DNS server, the best way to determine what needs to be changed is to see what device is being used as the DNS server for client workstations that are receiving DHCP from the network. This information is typically in the DNS section of the network adapter settings on the client workstation.

Step2. Click [Device Management].Step3. Click [DHCP].

Step4. Click [DHCP Server].Step5. Click [Edit].Step6. Enter “208.67.222.222” in the [DNS Server 1] field.

Step7. Enter “208.67.220.220” in the [DNS Server 2] field.Step8. Click [Apply].

Appendix-Transition Guide

Most Next-Generation Firewalls (NGFWs) reduce risk by providing access control over applications and users. But they don’t eliminate threats because attackers can still exploit open web connections and approved applications. For superior protection, an NGFW must be able to provide deep visibility into and across the network, apply intelligent automation to identify threats, adapt protections to a dynamic network environment, and quickly scope and recover from attacks to minimize damage. Cisco ASA with Firepower Services delivers all of those capabilities, so upgrade to Cisco’s newest NGFW today and protect your high-value digital assets.
