Create a new tunnel
Define the remote gateway IP, pre-shared key (for IPsec), or server certificate (for SSL VPN)
Step 2: Configure Phase 1 and Phase 2 Parameters
Select encryption algorithms like AES-256 and SHA-256
Define local and remote subnets
Enable NAT traversal and Dead Peer Detection (DPD)
Step 3: Set Up User Authentication
Create VPN user groups and users under User & Device > User Definition
Assign roles for different levels of access
Enable 2FA with FortiToken or external services (e.g., Google Authenticator)
Step 4: Create Security Policies
Go to Policy & Objects > IPv4 Policy
Allow traffic from VPN interfaces to internal resources
Use Identity-Based Policies to restrict access to authorized users only
Step 5: Enable Logging and Monitoring
Use FortiView and Log & Report tools to track login attempts, traffic usage, and anomalies
Optional: Integrate with FortiAnalyzer for advanced logging and compliance reporting
