How to view dhcp client list1/1/2023 The DHCP server must have appropriate routing so that its response packets to the DHCP clients arrive at the unit. The interface forwards DHCP requests from DHCP clients to an external DHCP server and returns the responses to the DHCP clients. You can configure a FortiGate interface as a DHCP relay. The routers must be configured for DHCP relay. The IP range of each DHCP server must match the network address range. If an interface is connected to multiple networks via routers, you can add a DHCP server for each network. The host computers must be configured to obtain their IP addresses using DHCP. A DHCP server dynamically assigns IP addresses to hosts on the network connected to the interface. You can configure one or more DHCP servers on any FortiGate interface. You can configure an IPsec DHCP server on an interface that has either a static or a dynamic IP address. However, you can configure a Regular DHCP server on an interface only if the interface is a physical interface with a static IP address. An interface cannot provide both a server and a relay for connections of the same type (regular or IPsec). 4.Note that DHCP server options are not available in transparent mode.Ī DHCP server provides an address to a client on the network, when requested, from a defined address range. Then, we can update the file for missing information like lease start-end, etc., with information obtained from dhcpd.leases file. However, we can parse the dhcpd.log file to search for ack lines. Parsing the dhcpd.leases file also does not give any information as to when was the last time a dhcp ack was sent to the machine. Nevertheless, this information is incomplete. Now, let’s discuss in little detail each parameter that appears in dhcpd.leases file. Let’s see the file’s content: $ more /var/lib/dhcpd/dhcpd.leases lease file path is: /var/lib/dhcpd/dhcpd.leases
