Looking for Concurrent Explicit Proxy User Limits on High-End FortiGates

[FortiPenny]

The customer currently has approximately 50k concurrent explicit proxy users, and we are trying to identify a suitable FortiGate/FortiProxy model or scalable architecture to support this requirement.

Unfortunately, we haven’t been able to find publicly available documentation that clearly states the maximum supported value for “Concurrent Explicit Proxy Users” on most FortiGate models.

So far, we have confirmed the following:

• FortiProxy 4000G – 60k users (from published specifications)

• FortiGate 901G – 32k users (observed from device login)

• FortiGate 1001F – 32k users (observed from device login)

Could anyone please confirm the supported values for the following models?

• FortiGate 1800F

• FortiGate 2600F

• FortiGate 3000F

If you have access to the device, the value can be found under:
System → Global Resources → User & Device → Default Maximum

Any insights or confirmations would be greatly appreciated. Thank you.

FortiGate 1800F - 32k concurrent proxy users
FortiGate 2600F - 64k concurrent proxy users
FortiGate 3001F - 128k concurrent proxy users

config system resource-limits
set proxy ? would show the min and max values

Many thanks for your help, RBA!
