The EdgeRouter PoE is 5 ports only (the sixth port you see is the console port, serial, not ethernet, and not useable as WAN or LAN).
There is a Load Balancing Wizard built into the GUI, I believe.
The latest Wizard now allows you to add additional WAN ports into the Load Balancing Group, so you could in theory do your 4 WAN + 1 LAN on this device via that Wizard (as Flipper mentions).
