The sponsor's administrative profile defines the scope of management permissions, including which accounts they can create, view, and modify. By restricting the administrative profile to a specific department, each sponsor can manage only their own department's contractor accounts and not those of other departments.

In a FortiNAC-F deployment, the configuration of the DHCP scope for isolation networks (Registration, Remediation, etc.) must perfectly align with the underlying network infrastructure to ensure that isolated hosts can communicate with the FortiNAC appliance. In the provided exhibits, there is a clear discrepancy between the DHCP configuration and the Network Topology.
As shown in the "Network Topology" exhibit, the Registration Network resides on a router interface (or sub-interface) with the IP address 192.168.180.1. This address represents the default gateway for any host placed into the Registration VLAN. However, the "DHCP configuration" exhibit shows the scope "REG-ScopeOne" configured with a Gateway of
10.0.1.254. This 10.0.1.254 address belongs to the management/service network (port2 of FortiNAC), not the registration subnet. If a host in the Registration VLAN receives this incorrect gateway via DHCP, it will attempt to send all off-link traffic to an unreachable IP, preventing it from loading the Captive Portal or communicating with the FortiNAC server.
According to the FortiNAC-F Configuration Wizard Reference, when defining a Layer 3 network scope, the "Gateway" field must contain the IP address of the router interface that acts as the gateway for that specific isolation VLAN. The FortiNAC appliance itself usually sits on a different subnet, and traffic is directed to it via the router's DHCP Relay (IP Helper) and DNS redirection.
"When configuring scopes for a Layer 3 network, the Gateway value must be the IP address of the router interface for that subnet. This allows the host to reach its local gateway to route traffic.
If the gateway is misconfigured, the host will be unable to reach the FortiNAC eth1/port2 interface for registration... Ensure the Gateway matches the network topology for the isolation VLAN."
