There could be several reasons why DHCP is not giving out IP addresses after a machine restart in Sangfor NGAF. Here are some possible reasons and troubleshooting steps you can take:

1.DHCP service not running: Make sure the DHCP service is running on the NGAF device. Check the DHCP service status in the NGAF web console or command-line interface (CLI).

2.Incorrect DHCP configuration: Verify that the DHCP configuration is correct, including the IP address range, subnet mask, default gateway, and DNS server settings. Check for any typos or mistakes in the configuration.

3.IP address conflicts: Make sure there are no IP address conflicts on the network. Check for any duplicate IP addresses or misconfigured network devices.

4.Firewall settings: Check the firewall settings on the NGAF device to ensure that DHCP traffic is allowed to pass through.

5.Network connectivity issues: Check the network connectivity between the NGAF device and the DHCP server. Verify that the DHCP server is reachable and responding to requests.

6.Lease time: Check the lease time setting for the DHCP service. If the lease time is set too high, it could cause IP addresses to be unavailable for an extended period.

7.Other devices on the network: Check for any other devices on the network that may be causing issues with DHCP, such as rogue DHCP servers or misconfigured routers.
