If the Sangfor NGAF firewall's DHCP server does not give out IP addresses within one hour of a machine restart, there may be several possible issues to consider for example, The DHCP server service may not be running on the firewall. Check the DHCP server status on the firewall and start it if necessary.Also, The DHCP scope may not be configured properly on the firewall. Check the DHCP scope settings on the firewall and make sure it includes the range of IP addresses that the clients need. Another thing is the DHCP lease time may be set to a very long duration, and the clients are unable to obtain new IP addresses. Try shortening the lease time on the firewall.
