FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance, including encrypted traffic.
This article describes an issue where FortiGate-70G running v7.2.8 Build 6403 may experience interfaces becoming non-operational or stuck with no traffic after rebooting.
Scope
FortiGate-70G.
Solution
This behavior is caused by a software issue already addressed by Fortinet R&D.
For now, use the following workaround:
Configure the affected FortiGate-70G ports on a software switch instead of a hardware switch. Note that a reboot is required for the changes to take effect.
Fix:
Already addressed in a special branch of v7.2.11, it is released on build 6570 and in v7.4.8 (70G can be directly upgraded from v7.2.11 to v7.4.8 per the Upgrade Path Tool Table).
