![]() ![]() This will enable the ability to check the SNI to ensure there is no “confusion” as to what server name is being seen, hence removing the concern around overlapping IPs. If there is more than one, click the one that will require Umbrella Roaming Client interop.Įnsure, under “Advanced”, that the “Perform SNI (Server Name Indication) check” is selected like so: To ensure SNI checking is enabled, follow these steps:Ĭlick on the existing tenant configuration. Now that the SNI check option exists for steering, this option should not be needed. When this occurred, Netskope would “map” that IP to all of those applications, and policy could overlap. This was originally done by turning on “Ignore DNS Loopback” in the backend to ensure there was no “overlapping IP space” when one IP was used by several applications. #3 - Enable “Perform SNI (Server Name Indication) check” (CASB mode ONLY!) Watch this SHORT VIDEO to see how to create these exceptions (required MacOS processes are shown in video). This will prevent Netskope from intercepting any traffic from the DNSCrypt component of Umbrella, as well as ensure that no traffic bound to the Umbrella dashboard (for things like updating status/operation) is intercepted by Netskope.įor Windows AND MacOS Umbrella RC, create a single Cert-Pinned App with the following listed as processes:įor the Umbrella DNScrypt process: “dnscrypt-proxy.exe”, soon to be “dnscryptproxy.exe” as of 2.3+ of the Umbrella Roaming Clientįor the Umbrella RC process: “ercservice.exe”įor the Anyconnect with the Umbrella Roaming Module: “acumbrellaagent.exe”. This step is done for Umbrella components running on the host, but even if the Umbrella user is just redirecting via virtual appliances while on-prem, it’s not a bad idea to have these bypasses in place. #2 - Bypass Umbrella Processes for Umbrella DNS-based protection When finished, the Network Location should look like this: This will prevent Netskope from intercepting the block page responses and the Intelligent Proxy redirect responses (if enabled in Umbrella), regardless of type (malware, malsite, content, etc) so those pages/redirects can be properly rendered. Regardless of the Netskope steering method (CASB or NG-SWG) or OS (Windows or Mac), create a Network Location and add the below ranges to it. THIS DOCUMENTED WAS CREATED USING THE FOLLOWING COMPONENTS:Ĭisco An圜onnect (v.5) w/Latest Umbrella Roaming Module as of ![]() This guide will show you how to implement the steps to ensure smooth interoperability between the two solutions. If you're currently using Cisco Umbrella in your organization, you might have experienced some issues when running Netskope and Cisco Umbrella together. ![]()
