Pppoe connections and load balancing

[tonysud]

hi
questions:

1. how many pppoe connections pfsense can handle?
is there a limit? for example can it work with 15 active pppoe connections?
I have routers in bridge so, I could establish pppoe connections from pfsense

2. load balancing problem
imagine this situation:
pc1 with ip 192.168.20.20 and pfsense with ip 192.168.20.30
pfsense has 10 pppoe active connections (= 10 public IP)

on PC1, the default gateway is pfsense ip (192.168.20.30)
on PC1 I have linux installed, and I need to do this:

wget http://mycompanysite.com/file.zzz (a lot of times)

I need to do this: each time I wget a file from the same host (mycompanysite.com) I need to switch the WAN used
so for example, one time I use WAN1, another time I use WAN3, another time I use WAN 6, and so on
also randomly… no problem

How to configure pfsense so that it can load balancing traffic to the same destination host to use all wan/pppoe connections?
