Check Point gateway as DHCP server : A Real-World Scenario

Welcome to this hands-on guide on configuring your Check Point gateway as a DHCP server. 🚀 In this video, we’ll explore not only how to set it up, but also why you might want to use your gateway for DHCP. From small branch offices to large enterprise environments, this feature has powerful use cases. 👉 Why use your gateway as DHCP server? One of the most important scenarios is in isolated or DMZ networks. In these high-risk zones, exposing internal DHCP servers is a security concern. By enabling DHCP directly on the gateway, you: Keep IP assignment local Reduce your attack surface Enforce strict segmentation Avoid routing DHCP requests into the trusted network Your gateway becomes the gatekeeper—not only for traffic, but also for identity. What you’ll learn in this video: Step-by-step configuration process in Gaia How to create a bond interface (bond0) and add eth0 and eth2 without IPs Creating VLAN interfaces on the Check Point gateway Setting up a port-channel on a Cisco switch: interface range GigabitEthernet 0/0 - 1 switchport mode trunk channel-group 1 mode active interface Port-channel1 switchport mode trunk Creating matching VLANs on the switch and assigning client interfaces Configuring the DHCP server and adding subnets on Check Point Ensuring the security policy allows all traffic on the gateway Testing DHCP with a virtual PC (ip dhcp) to verify it receives an IP Reserving a specific IP for a client by editing /etc/dhcpd.conf: host my-client { hardware ethernet 00:50:79:66:68:06; fixed-address 172.22.15.77; option routers 172.22.15.1; option subnet-mask 255.255.255.0; option domain-name-servers 8.8.8.8; } Restarting the DHCP service to apply changes: service dhcpd restart This isn’t just theory—it’s a practical demo that reflects real deployments and real security needs. By the end, you’ll be able to configure DHCP on your Check Point gateway with confidence. #CheckPoint #DHCP #NetworkConfiguration #GaiaOS #NetworkSecurity #DMZ #GuestNetwork #EnterpriseNetworking #FirewallConfiguration #ITTraining
