Deploy a FortiGate 60F in 1 hour flat for a 20-person SME

·8 min read

Step-by-step guide to deploying a FortiGate 60F firewall on a 20-person SME: initial configuration, rules, IPsec VPN, monitoring. In 1 hour flat.

You've just received your FortiGate 60F and you have 1 hour before the end of the day. It's doable. Here's the sequence we apply in the field to have a functional and reasonably secure firewall in 60 minutes.

Prerequisites (5 min)

  • FortiGate 60F unboxed and powered up
  • RJ45 cable on WAN1 port to the ISP gateway
  • RJ45 cable on LAN port to internal switch
  • Laptop connected to LAN with DHCP IP by default (192.168.1.x)
  • FortiCloud account created (free, required for license)

Step 1 — First login + reset password (5 min)

  • Navigate to https://192.168.1.99 from the laptop
  • Login: admin / no password by default
  • Set a strong admin password (16+ characters)
  • Immediately enable 2FA via FortiToken Mobile (free)

Step 2 — License registration + updates (10 min)

  • System > FortiGuard: register the device on FortiCloud with the serial
  • Verify that FortiGuard services appear green (AV, IPS, Web Filter)
  • System > Firmware: move to latest stable LTS version if needed (reboot ~3 min)

Step 3 — WAN configuration (5 min)

  • Network > Interfaces > wan1: DHCP if ISP gateway provides an IP, otherwise Manual with IP/gateway/DNS
  • Verify internet connectivity: Diagnostics > Ping to 1.1.1.1

Step 4 — LAN configuration (5 min)

  • Network > Interfaces > internal: 192.168.10.1/24 (change from default 192.168.1.x to avoid conflict with other networks)
  • Enable DHCP server: pool 192.168.10.100-199, DNS 192.168.10.1 (FortiGate acts as DNS)
  • Reconnect the laptop, wait for new IP

Step 5 — Basic security policy (15 min)

Policy & Objects > Firewall Policy. Create 3 minimum rules:

  • LAN → WAN: Source internal, Destination wan1, Service ALL, Action ACCEPT, Inspection: AV + IPS + Web Filter + Application Control + DNS Filter enabled
  • WAN → LAN: no rule (everything is blocked by default, perfect)
  • LAN → LAN segments: if separate VLAN servers, create strict inter-VLAN rules

Step 6 — Web filtering + block risky categories (5 min)

  • Security Profiles > Web Filter: block Adult, Gambling, Malware, Phishing, Cryptomining, Unrated
  • Enable SafeSearch on Google/YouTube (option at bottom)
  • Link this profile to the LAN → WAN rule

Step 7 — SSL VPN for remote work (10 min)

  • VPN > SSL-VPN Settings: interface wan1, port 10443 (not 443 to avoid conflict), initial self-signed certificate authentication
  • Create a "remote-users" user group + test users
  • Create firewall policy ssl.root → internal for the group
  • Test from FortiClient on smartphone 4G

Step 8 — Logging + alerting (5 min)

  • Log & Report > Log Settings: send to FortiCloud Free (free 7-day logs)
  • Enable email alerts for: admin login, critical IPS, critical AV, discovered vulnerability
  • Test alert with failed admin login

Summary: 60 minutes for what?

You now have: firewall with strict rules, IPS + AV + web filter active, functional SSL VPN, cloud logging, email alerts, admin 2FA, strong password. This is well above the security level of 80% of French SMEs.

What remains to be done next week

  • Replace self-signed certificate with Let's Encrypt
  • Segment into VLANs (servers / workstations / IoT / guests)
  • Enable SD-WAN if multiple internet links
  • Document in a runbook (who changes what, how to restore config)
  • Backup FortiGate config to external cloud (encrypted config)

Conclusion

A well-configured FortiGate 60F in 1 hour is a massive security leap for an SME. If you don't have the time or inclination, KOLOSALTech deploys this type of configuration in 1/2 day including documentation and end-user training.
