Fortinet FortiGate to Palo Alto Migration
Moving from FortiOS to PAN-OS? NetConverter's comprehensive multi-step pipeline automates the conversion of firewall policies, VIPs, address objects, and service definitions with 95%+ accuracy and confidence scoring.
Why FortiGate → Palo Alto Is Mostly About NAT
If you're moving from FortiOS 7.4 to Palo Alto PAN-OS 11.2, the security policy model translates cleanly — both vendors use zone-based policy with named address/service objects. The hard part is NAT. FortiGate supports two NAT modes: per-policy NAT (NAT enabled inside a firewall policy) and central NAT (separate config firewall central-snat-map table). Most production FortiGates use a hybrid — central SNAT + per-policy DNAT via VIP objects. Translating to Palo Alto requires unifying these into PAN-OS's flat NAT policy table while preserving evaluation order.
The other migration killer: FortiGate VIP objects with port-forwarding (config firewall vip with portforward enable) need to split into Palo Alto destination NAT + service object pair. A FortiGate VIP forwarding tcp/8443 → 10.0.0.10:443 becomes (1) a PAN-OS address object for the public IP, (2) a service object for the original tcp/8443, (3) a service object for the translated tcp/443, and (4) a NAT rule chaining them. NetConverter handles this VIP-to-DNAT split automatically and validates the result with a packet-tracer simulation.
The Challenge of FortiGate to Palo Alto Migration
Policy Structure Differences
FortiGate uses policy IDs and interface-pair based rules, while Palo Alto uses zone-based security policies with different matching logic.
VIP to NAT Translation
Fortinet's VIP objects must be decomposed into Palo Alto address objects and NAT rules - a tedious manual process.
Service Definition Mapping
Custom services and service groups have different syntax and need careful mapping to preserve port definitions.
Address Object Conversion
Address objects, address groups, and wildcards need to be converted to Palo Alto's address object format.
How NetConverter Solves It
Vendor-Neutral Translation
Our comprehensive multi-step pipeline normalizes configurations to a unified format, enabling accurate translation between any vendor pair.
Intelligent Policy Migration
Policies are converted with proper zone mapping, maintaining security intent while adapting to Palo Alto's model.
Automated VIP Conversion
VIPs are automatically converted to the appropriate address objects and NAT rules with correct mappings.
Service Migration
All service objects and groups are converted with port definitions and protocols preserved accurately.
Complete Object Migration
Address objects, groups, and wildcards are converted with naming conventions maintained.
4-Tier Validation System
Every translation undergoes comprehensive validation: syntax correctness, semantic accuracy, vendor best practices compliance, and AI-assisted review.
Confidence Scoring
Each conversion includes a confidence score indicating translation quality, helping you prioritize review efforts and ensuring production readiness.

How does FortiGate central NAT translate to Palo Alto?
central-snat-map entries become Palo Alto NAT policies in source-NAT mode. Each entry's srcaddr + dstaddr + orig-port + nat-ippool maps to a PAN-OS NAT rule with bidirectional translation flagged appropriately. NetConverter preserves entry ordering — central SNAT order matters in FortiOS — and surfaces any rule that depends on FortiOS-specific behaviors (e.g., poolname referring to a depleted pool) in the Manual Steps section.What happens to FortiGate VIPs with port forwarding during migration?
portforward enable are split into a Palo Alto address object + service object pair + NAT rule. A VIP forwarding tcp/8443 → internal:443 becomes a PAN-OS address object, a service object for the external port (tcp/8443), a service object for the internal port (tcp/443), and a destination-NAT rule chaining them. The simulate_flow tool validates the resulting packet path post-migration.
