Enhanced security through smaller attack surfaces and least privilege access policies. On the Add IdP Configuration pane, select the Create IdP tab. So - the admin machine is able to resolve the remote machine via ZPA, and initiate the push. o TCP/464: Kerberos Password Change They must subscribe to a separate solution, Zscaler Internet Access, to manage their X-as-a-Service (XaaS) resources. no ability to use AD Site) configure IP Boundary with ALL RFC1918 addresses, DFS Consider the following, where domain.com is a globally available Active Directory. In a traditional remote access solution (VPN) the user is provided an IP address on the network (VPN DHCP Pool), which would be registered as an IP Boundary, or which would be part of an AD Site.
