How to load balancing between lan and adsl ?

[Dongsheng Song]

Hello forks,

My proxy use bnx1 connect to internal network, and bnx0 connect to inet.
Can I add adsl for load balancing ?

              |- ext_if(bnx0)
int_if(bnx1) -|
              |- adsl(tun1, bge0)

Thanks for some help,
Dongsheng
