System and Network Administration

This domain covers FortiGate system and network administration: interface and route configuration, policy routes, WAN link load balancing, transparent mode, firmware upgrades, and administrative access. Questions present a symptom (traffic ignoring PBR, unwanted load balancing) or a configuration scenario and ask which setting, mode, or step resolves it correctly.

What this domain covers

What to know about System and Network Administration

Be able to configure and verify policy routes, WAN link load balancing, transparent mode, and firmware upgrades on a FortiGate. The single most important thing: confirm a policy route actually matches the traffic by checking sequence, source, destination, and incoming interface before blaming the default route.

Configuring policy routes (PBR) with correct sequence, gateway, and incoming interface matching

Using SD-WAN or WAN LLB to control per-destination link selection

Applying FortiGate transparent mode behavior, including no IP on data interfaces

Planning firmware upgrade path and configuration backup before version changes

Watch out for

Common System and Network Administration exam traps

  • ▸Assuming PBR overrides everything: policy routes are evaluated before the routing table, but wrong sequence, source, or incoming interface makes them never match.
  • ▸Confusing WAN LLB with SD-WAN: LLB load-balances by destination, so a specific subnet may still spread across links unless excluded.
  • ▸Upgrading firmware without checking the supported upgrade path or taking a config backup, risking failed boot or lost settings.

A medium-sized enterprise has a FortiGate 100F in NAT/Route mode with three interfaces: port1 (WAN, 203.0.113.1/24, gateway 203.0.113.254), port2 (internal, 192.168.1.1/24), and port3 (DMZ, 10.0.0.1/24). The internal network hosts a web server at 192.168.1.10 and a mail server at 192.168.1.20. The DMZ hosts a public web server at 10.0.0.10 and a public DNS server at 10.0.0.20. The company has a single public IP 203.0.113.1. The administrator has configured the following: - Port forwarding: external HTTP to DMZ web server (10.0.0.10:80) and external DNS to DMZ DNS server (10.0.0.20:53). - Outbound NAT (IP Pool) for internal users to 203.0.113.1. - Firewall policies allowing internal to external, DMZ to external, and external to DMZ (for forwarded services). Users report that they can access the Internet but cannot reach the internal web server (192.168.1.10) via its public IP (203.0.113.1:80). The DMZ web server is accessible from the Internet.
