PPPoE Multi-WAN Loadbalance

[trumee]

Hello,
I have three interfaces defined on the pfSense router with the configuration in the table below. The second and third interfaces have the same gateway.

	WAN Type	ISP	Gateway	IP
1	PPPoE	ISP1	GW1	IP1
2	PPPoE	ISP2	GW2	IP2
3	PPPoE	ISP2	GW2	IP3

This article mentions that PPPoE interfaces with the same gateway can be used together with load balancing. I was able to confirm this by putting number 2 and 3 in a gateway group and load balancing worked.

However, i tried to put 1 and 2 in a gateway group but load balancing doesnt work. pfSense simply makes '1' as the default gateway and ignores the '2' interface. Is this configuration not supported?
Thanks
