Basic Setup
- Management IP: Set up the management IP address using the command:
“`config system interface
edit “mgmt”
set ip
end“`
2. Admin Account: Create an admin account with:
“`config system admin
edit “admin”
set password
end“`
3. Hostname: Define the hostname:
“`config system global
set hostname “FortiGate”
end“`
Interface Setup
- Physical Interface: Configure interfaces like `wan1` and
lan1:
“`config system interface
edit “wan1”
set mode static
set ip
end“`
2. VLAN Interface: Create VLANs:
“`config system interface
edit “vlan100”
set vlanid 100
set interface “internal”
set ip
end“`
- IP Address: Assign IPs to interfaces as shown above.
Security Policies
1. Policy Mode: Set NAT or Transparent mode:
“`config firewall policy
edit 0
set srcintf “lan1”
set dstintf “wan1”
set srcaddr “all”
set dstaddr “all”
set action accept
end“`
2. Source & Destination: Define IP ranges.
3. Services: Specify services like HTTP or FTP.
4. Action: Set to `accept` or `deny`.
NAT Configuration
1. Source NAT (SNAT): Hide internal IPs:
“`config firewall policy
edit 0
set nat enable
end“`
2. Destination NAT (DNAT): Map external IPs:
“`config firewall vip
edit “VIP1”
set extip
set mappedip
end“`
VPN Configuration
1. IPsec VPN: Configure a tunnel:
“`config vpn ipsec phase1-interface
edit “VPN_Tunnel”
set interface “wan1”
set peertype any
set proposal aes128-sha256
end“`
2. SSL VPN: Set up remote access:
“`config vpn ssl settings
set port 443
set tunnel-ip-pools “SSLVPN_TUNNEL”
end“`
Logging & Reporting
1. Logging: Enable logging:
“`config log setting
set status enable
end“`
2. Reporting: Configure reports:
“`config report setting
set report-source fortigate
end“`
Additional Features
1. DHCP: Configure DHCP:
“`config system dhcp server
edit 1
set interface “lan1”
set default-gateway
end“`
2. DNS: Set up DNS:
“`config system dns
set primary
end“`
3. Web Filtering: Enable URL filtering:
“`config webfilter profile
edit “default”
set block-malicious-url enable
end“`
What Undercode Say
FortiGate firewalls are essential for securing networks, and their configuration requires precision. Start by setting up the management IP and admin credentials. Configure physical and VLAN interfaces, ensuring proper IP addressing. Implement security policies to control traffic flow, and use NAT to protect internal IPs. VPNs like IPsec and SSL ensure secure remote access. Logging and reporting are critical for monitoring and compliance. Additional features like DHCP, DNS, and web filtering enhance network functionality and security.
For advanced configurations, explore FortiGate’s CLI commands:
- Use `diagnose debug` for troubleshooting.
- Apply `execute` commands for real-time actions, like
execute ping <IP>. - Leverage `show` commands to display configurations, e.g.,
show full-configuration.
