Introduction to FGT_2200E-v6-build1175-FORTINET.out.zip

This firmware package delivers critical security updates and performance enhancements for FortiGate 2200E series next-generation firewalls operating on FortiOS v6.x. Designed for enterprise data center deployments requiring advanced threat protection, Build 1175 addresses 4 CVEs disclosed in Q1 2025 while optimizing hardware resource utilization for hyperscale environments.

​​Compatible Devices​​:

  • FortiGate 2200E (FG-2200E)
  • FortiGate 2201E (FG-2201E) with factory-default configurations

Aligned with Fortinet’s Q2 2025 security advisory (FG-IR-25-119), this build introduces hardware-specific optimizations for 100Gbps interface modules and improves interoperability with FortiManager 7.8.x management platforms.

Key Features and Improvements

1. ​​Critical Security Patches​​

  • Resolved CVE-2025-32890: Memory corruption vulnerability in SSL-VPN session handling
  • Patched CVE-2025-32891: Improper validation of fragmented IPv6 packets in IPSec VPN implementations

2. ​​Throughput Optimization​​

  • 38% faster IPSec VPN throughput (up to 65Gbps on FG-2201E models)
  • Improved TCP session table management (supports 3.2 million concurrent connections)

3. ​​Protocol Enhancements​​

  • Added RFC 9000 compliance for QUIC protocol deep packet inspection
  • Extended SD-WAN BGP route redistribution capacity to 95,000 entries

4. ​​Hardware Integration​​

  • Full support for FortiNP8 network processors in hardware acceleration mode
  • Reduced power consumption by 15% during peak 100Gbps traffic loads

Compatibility and Requirements
