What Is Umbrella Roaming Client3/18/2021
Press question mark to learn the rest of the keyboard shortcuts Log in sign up User account menu 4 Cisco Umbrella DNS.First, from my understanding, if a client installs the Cisco Umbrella Roaming Client on their computer the installation process changes the default DNS server to localhost:53, which then proxies the DNS lookup to the Umbrella server.
What Is Umbrella Roaming Client Password Found OnIs there anything from stopping a user from manually changing their DNS settings to use a public DNS server such as 9.9.9.9 Put another way, Is there an administrative lock on the Roaming Client (similar to Sophos where to make any changes you need a unique Administrator password found on the Sophos portal) that locks down the DNS lookup Secondly, how does the IP - Layer Enforcement work Are users restricted from entering IP addresses manually into their web browsers or is the enforcement simply IP-Filtering using blackwhitelists that does(nt) allow connections from specific IP addresses Thanks in advance 6 comments share save hide report 76 Upvoted This thread is archived New comments cannot be posted and votes cannot be cast Sort by best level 1 3 points 1 year ago If the agent service is running in the background and a user changes their DNS, the agent will change it back to localhost.Granted they can just stop the service if they have permission.For example, in my network my local domain is example.local, my DNS server is at 10.0.10.10, and my DHCP server hands out this information. With the Umbrella Roaming Client running, the client sees 127.0.0.1 as the DNS server if they run ipconfig. If you stop the UmbrellaRC service and run ipconfig, youll see 10.0.10.10 as the DNS server. Queries for example.local will go to 10.0.10.10. I am not sure how the UmbrellaRC service will direct queries for other domains. Unfortunately I dont have an explicit answer for either of your actual questions. Ive never thought to check if a manual reconfiguration of the DNS server actually changes the masked server. Ive always killed the UmbrellaRC service when troubleshooting DNS so Ive never noticed. ![]() As for IP Layer enforcement, Ive actually never heard of it and Im not sure if we use it or not. In my experience however, I can still type straight IPs into the browser, although we only do so for internal stuff so, your mileage may vary. Of course, if you are worried about people overriding the client, make sure they do not have local Admin. Itll capture anything that isnt using DNS and do its filterproxy as needed.
