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.


FortiLink uses the following protocols:
HTTPS (TCP 443) for control
CAPWAP (UDP 5246-7) for legacy functions, SW upgrades etc.
If HTTPS access or CAPWAP access is disabled on the downstream device, it may be unable to communicate with the FortiGate on the FortiLink, resulting in undesired behaviour.
