We already configure our QEMU in GNS3 and run our vSRX Router. Now its time to configure DHCP server in our vSRX router. Lets began.
Logical Diagram for this tutorial
To configure DHCP server
Assign Lowest and highest IP range
root# set system services dhcp pool 192.168.1.0/24 address-range low 192.168.1.50 high 192.168.1.200
Assign DNS server (in my case I had used Router interface IP)
root# set system services dhcp pool 192.168.1.0/24 name-server 192.168.1.1
Assign IP address of the router
root# set system services dhcp pool 192.168.1.0/24 router 192.168.1.1
Assign the lease time
root# set system services dhcp pool 192.168.1.0/24 default-lease-time 3600
Assign DHCP as an allowed inbound service for the interface which we are going to enable DHCP.
root# set security zones security-zone untrust interfaces ge-0/0/1 host-inbound-traffic system-services dhcp
Assign IP address to the client faced interface.
root# set interfaces ge-0/0/1 unit 0 family inet address 192.168.1.1/24
Check our client get the IP Address from the server.

How to statically assign IP with fixed MAC address
root#set system service dhcp static-binding 00:50:79:66:68:00 fixed-address 192.168.1.100
PC1>show ip
Request DHCP IP
PC1>dhcp -d
