Specifying a domain name suffix for DHCP clients on a FortiGate (FortiOS)

Domain Name Suffix

You can specify a domain name suffix in a DHCP address pool on the FortiGate DHCP server. With this suffix assigned, the client only needs to input part of a domain name, and the system adds the domain name suffix for name resolution. For example a client can type in https://fortimanager in their web browser to access your fortimanager instance, instead of the FQDN of https://fortimanager.domain.local

In FortiOS (current as of December 2022) this is configured via the CLI.

 


Configuration

config system dhcp server
    edit <#>
        set domain <domain suffix>

 

In a full context this would be

config system dhcp server
    edit 1
        set domain "lab.example.com"
        set default-gateway 192.168.1.1
        set netmask 255.255.255.0
        set interface "port1"
        config ip-range
            edit 1
                set start-ip 192.168.1.100
                set end-ip 192.168.1.200
            next
        end
        set dns-server1 8.8.8.8
        set dns-server2 8.8.4.4
    next
end

NSE8 Lab Study Resources - Narbik CCIE R&S v5.1 Foundations

Image
 Hey All, I have been working on putting together some scenarios for lab practice and I've found myself falling back on some of the study materials I used when preparing for the CCIE EI (yet to obtain, on the list after the NSE8). A legendary trainer in this area is Narbik Kocharians CCIE 12410 who is the president of Micronics Networking and Training - his CCIE prep courses and text books are considered almost required reading for any serious candidate for this certification. His text books work through hands on labs that are focused on specific topics to help cement the theory of the different topics in the exam.  His textbook CCIE Routing and Switching 5.1 Foundations: Bridging the Gap between CCNP and CCIE is well aimed at the skill level required of the NSE8 and fortunately there is actually quite a bit of overlap in its 1100 pages. The chapters within the textbook are: 1. Physical Topology 2. Physical and Logical Topologies 3. Spanning Tree Protocol 4. Point-to-Point Protocol

Journey to the NSE8 - Change in tactic

 I've previously been studying the Secure Wireless LAN content in order to pass the final exam required for my NSE6 (on the way to the NSE8). Going over the material again at the moment I'm noticing that my study sessions are becoming a bit of a blur and I'm not absorbing the content as well as I should be, and I can see this track of study becoming like quicksand if I don't give myself a break from it. The NSE6 fortunately covers a lot of technologies, including FortiAuthenticator and FortiADC which are both heavily featured on the NSE8 blueprint. So from here Im going to review the training for the FortiADC and have a crack at that exam to finish off my NSE6
