Explore IT Issues: Solutions For All FortiGate Firewall Setup: How to Configure Internet Access Step-by-Step (2026) | Firewall Training Phase 1: Interface Configuration You must first define who is the "Outside" (ISP) and who is the "Inside" (Users). WAN Setup: Go to Network -- Interfaces. Edit your wan1 (or equivalent) port. Role: WAN. Addressing Mode: Select DHCP (typical for home/small biz) or Manual (enter your Static IP/Subnet from your ISP). LAN Setup: Edit your internal or lan port. Role: LAN. IP/Network Mask: Assign your local gateway (e.g., 192.168.1.1/24). DHCP Server: Enable this so your computers get IPs automatically. Phase 2: The Default Route (The Way Out) Without a route, the firewall doesn't know where the "Internet" is. Go to Network -- Static Routes. Click Create New. Destination: 0.0.0.0/0.0.0.0 (This means "Anywhere"). Gateway: Enter the IP of your ISP’s router. Interface: Select your wan1 port. Click OK. Phase 3: The Firewall Policy (The Permission) By default, FortiGate blocks everything. You must create an "Allow" rule. Go to Policy & Objects -- Firewall Policy. Click Create New and name it Internet_Access. Incoming Interface: LAN (or your Internal port). Outgoing Interface: WAN1. Source / Destination / Service: Set all to all/ALL. Action: ACCEPT. NAT: Ensure the NAT toggle is ON (This is the most common reason internet fails if missed). Phase 4: DNS (The Phonebook) Ensure the firewall can resolve names like google.com. Go to Network -- DNS. Select Use FortiGuard Servers or specify Manual (e.g., 8.8.8.8). Click Apply. FortiOS 7.6, Fortinet Tutorial, Firewall Policy NAT, Static Route Setup, Initial Configuration
