PfSense 2.0 Gateway Tier question

[stramato]

In 2.0, Systems>Gateway Groups

We assign Tiers for each WAN connection.

Example I do this for my internet connections:

WAN: Tier1
OPT1: Tier2
OPT2: Tier3

So pfSense Load Balancer will max out WAN 1st, then if it's max'd out, proceed using OPT1, then if it's max'd out, proceed using OPT2?

alternatively, if the scenario is as with below:

WAN: Tier1
OPT1: Tier1
OPT2: Tier1

It will Round Robin Load Balance between the 3 internet connections.

Is this correct? Or is my understanding wrong?

That is not how they work.

The tiers are for failover. In your first scenario, OPT1 would be used if WAN died. OPT2 would be used if both WAN and OPT1 died.

The second scenario is correct. WANs on the same tier are round-robin connection balanced.
