zscaler application access is blocked by private access policy

Currently, we have a wildcard setup for our domain and specific ports allowed. From an Active Directory perspective you may create an application segment for each regions or countries AD Servers a company may have 1000 Domain Controllers across 100 countries, and a single Application Segment with 1000 entries may not be manageable. Zscaler secure hybrid access reduces attack surface for consumer-facing applications when combined with Azure AD B2C. Eliminate the risk of losing sensitive data through vulnerable clients and infected endpoints with integrated cloud browser isolation. 600 IN SRV 0 100 389 dc2.domain.local. Similarly AD Site can be implemented where a robust replication policy exists, and a (relatively) flat/routed network exists. In steps 3 & 4 the client requests/receives the TGT from the Domain Controller, and subsequently requests/receives service tickets and TGT for the cross-realm. Watch this video to learn about ZPA Policy Configuration Overview. During registration, in Upload your policy, copy the IdP SAML metadata URL used by Azure AD B2C to use later. Depending on the client AD Site and the AD Site for the mount points, the client will establish a connection with the most efficient server. The issue now comes in with pre-login. Technologies like VPN make networks too brittle and expensive to manage. This allows access to various file shares and also Active Directory. Request an in-depth attack surface analysis to see what apps and services you have exposed to the internet, vulnerable to attacks. Verify to make sure that an IdP for Single sign-on is configured. Need some design changes in our environment and it's in WIP now is your problem solved or not yet? Going to add onto this thread. Appreciate the response Kevin! Zero Trust Architecture Deep Dive Summary will recap what you learned throughout your journey to a successful zero trust architecture in the eLearnings above. Register a SAML application in Azure AD B2C. SCCM can be deployed in IP Boundary or AD Site mode. Understanding Zero Trust Exchange Network Infrastructure will focus on the components of Zscaler Private Access (ZPA) and the way those components shape the architecture and infrastructure of a Zero Trust Network. Migrate from secure perimeter to Zero Trust network architecture. An important difference is that this method effectively uses the connections source IP address (as seen by the CLDAP process) instead of the client communicating its interface addresses. Introduction to Zscaler Digital Experience (ZDX), Learn about common ZDX configuration tasks, Troubleshooting User Experience Problems with ZDX, Supporting Users and Troubleshooting Access. We tried using ZPA connector IPs as a AD site, but not helping as SCCM is picking the client's local IP. 600 IN SRV 0 100 389 dc7.domain.local. In a scenario where the SCCM deployment is IP Boundary, it is conceivable to configure specific AD Sites for Zscaler Private Access App Connectors, and use these sites to control SCCM Distribution points. Getting Started with Zscaler Internet Access. Intune, Azure AD, and Zscaler Private Access - Mobility, Management We absolutely want our Internet based clients to use the CMG, we do not want them to behave as On prem clients unless they are indeed on prem. ZIA is working fine. Once i had those it worked perfectly. Watch this video to learn about the purpose of the Log Streaming Service. ZPA is policy-based, secure access to private applications and assets without the overhead or security risks of a virtual private network (VPN). The query basically says - what is the closest domain controller for me based on my source IP. When users access cloud resources, VPN gateways channel the traffic in both directions through the private network. -James Carson Copy the Bearer Token. A site is simply a label provided to a location where Domain Controllers exist. Formerly called ZCCA-PA. Watch this video to learn how about the SAML Attributes page and why it is important to configure SAML attributes. o TCP/8530: HTTP Alternate Dynamic Server Discovery group for Active Directory containing ALL AD Connector Groups \UK1234CSC123.company.co.uk\dfs and \UK1923C4C780.company.co.uk\dfs could have a single segment containing UK1234CSC123.company.co.uk and UK1923C4C780.company.co.uk as theyre the same mount point), The following recommendations are made when deploying Active Directory, SCCM, and DFS with Zscaler Private Access. The resources themselves may run on-premises in data centers or be hosted on public cloud . With all traffic passing through Zscalers cloud, latency depends on the distance to the nearest Private Server Edge. Click on Next to navigate to the next window. So - the admin machine is able to resolve the remote machine via ZPA, and initiate the push. They used VPN to create portals through their defenses for a handful of remote employees. This would also cover *.europe.tailspintoys.com and *.asia.tailspintoys.com as well as *.usa.wingtiptoys.com since the wildcard includes two subdomains resolution. Im looking specifically into an issue with traffic from third party software not being allowed to the loopback interface (localhost) while ZPA is enabled and Im not getting CORS errors.

Twingate, by comparison, turns each user device into its own point of presence (PoP) by creating direct connections to resources along the most efficient, performant path. Connector Groups dedicated to Active Directory where large AD exists ServerGroup = ALL APP Connectors contains WDC App Connector Group, Arkansas App Connector Group, California App Connector Group, Florida App Connector Group. If not, the ZPA service evaluates policies on the users it does not recognize. Zscaler Private Access and SCCM. Under IdP Metadata File, upload the metadata file you saved. Its clearly imperative that the ZPA App Connector can perform internal DNS resolution across the domain, and connect to the Active Directory Domain Controllers on the necessary ports UDP/389 in particular. This ensures that search domains do not leak to the internet and ZPA is tried for all domains internally first. Apply ML-based policy recommendations trained by millions of customer signals across app telemetry, user context, behavior, and location. Take a look at the history of networking & security. Upgrade to the Premium Plus service levels and response times drop to fifteen minutes. Section 1: Verify Identity & Context will allow you to discover the first stage for building a successful zero trust architecture. Enterprise tier customers get priority support services. Hi Kevin! The Zscaler client app enforces access policies on the users device before initiating a proxy connection to its closest Zscaler data center. Verifying Identity and Context will enable you to understand user and device authentication processes to access private applications using Zscaler Private Access (ZPA). Note that if this option somehow dynamically flips the always Internet configuration of the ConfigMgr client, this is explicitly unsupported, so I'd strongly suggest caution with using this feature. When users need access, the Twingate Client app enforces security policies. Wildcard application segments for all authentication domains Zero Trust Architecture Deep Dive Introduction. WatchGuard Technologies, Inc. All rights reserved. How we can make the client think it is on the Internet and reidirect to CMG??

Navigate to portal.azure.com or devicemanagement.microsoft.com and select "Client apps -> Apps". The push actually triggers the remote machine to pull the content from SCCM Management/Distribution point. We absolutely want our Internet based clients to use the CMG, we do not want them to behave as On prem clients unless they are indeed on prem. Click Test Connection to ensure Azure AD can connect to Zscaler Private Access (ZPA). And MS suggested to follow with mapping AD site to ZPA IP connectors. Hi @CSiem o TCP/135: MSRPC But we have an issue, when the CM client tries to establish its location it thinks it is an Intranet managed device as its global catalog queries are successful. The ZPA Admin path covers an introduction and fundamentals of the Zscaler Private Access (ZPA) solution. You can add a HTTPS packet filter To: 165.225.60.24 or the domain name being accessed, which allow the desired access. A cloud native service, ZPA can be deployed in hours to replace legacy VPNs and remote access tools with a holistic zero trust platform, including: Connect users directly to private apps, services, and OT systems with user identity-based authentication and access policies. This article Zscaler Private Access - Active Directory Enumeration provides details of a script which can be run on the App Connector to ensure connectivity to the Domain Controllers, and identify the AD Sites and Services returned. Scroll down to provide the Single sign-On URL and IdP Entity ID. If no IdP is setup, then add one by clicking the plus icon at the top right corner of the screen. Also blocked on-prem MP traffic over ZPA and thought devices will be re-directed to CMG, no luck with that too. The Domain Controller Enumeration process occurs similar to how Site Enumeration occurs (previous section), however this time it will also look up across trust relationships. The workstation would issue a subsequent request for _LDAP._TCP.ENGLAND._sites._dc._msdcs.DOMAIN.COM which would return the UKDC.DOMAIN.COM which would process the remainder of the Netlogon and GPO requests. o *.otherdomain.local for DNS SRV to function In the example above, where the DFS mount point was \company.co.uk\dfs, and the referrals were to servers \UK1234CSC123\dfs and \UK1923C4C780\dfs it would be necessary to have a domain search of company.co.uk in order for these to be completed to \UK1234CSC123.company.co.uk\dfs and \UK1923C4C780.company.co.uk\dfs. Tutorial: Configure Zscaler Private Access (ZPA) for automatic user If the ICMP response is over a certain threshold, or fails to respond, then the link is deemed slow and fails to mount. Thanks Mark will have a review of the link, most appreciated. Yes, support was able to help me resolve the issue. ZIA Administrator Introduction aims to outline the structure of the ZIA Administrator course and help you build the foundation of your ZIA knowledge. The 165.225.x.x IP is a ZScaler cloud server that the PC client connects to. I edited your public IP out of your logs. This is counterintuitive since you would expect to use the ZPA connector closest to each of them, however as far as AD Sites is concerned we need to pass through the closest connector to user for all these requests since the source IP for any of these requests is used to identify the Client SITE for subsequent Active Directory request. The workstation needs to ascertain which domain controller(s) it should connect to for authentication and how to retrieve its Group Policy. Or subscribe to our free Starter tier to see how individuals and small teams benefit from Zero Trust access. Go to Enterprise applications, and then select All applications.
