What is fnSysOpMode?

This reports whether the FortiGate is running in nat(1) or transparent(2) operational mode. Admins check this to confirm the firewall is deployed as a routed NAT gateway versus a transparent Layer 2 bridge, which changes how traffic and policies are interpreted.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.12356.1.7
snmpwalk -v2c -c public <target> FORTINET-MIB-280::fnSysOpMode

Get a specific instance (index 1):
