TEQL with two ADSL connection

Hi all,
in my school I have:
- two Netopia router for ADSL (perform NAT),
- one linux box with 3 ethernet card

I want to make a load balancing on the two ADSL line.

I have configured the system as follow:

The LAN interface, of the two ADSL router, have address
(A) 192.168.0.254
(B) 192.168.2.254
The 3 ethernet card, on the linux box, have address:

-eth2   172.16.255.254, connected to a switch and operate with VLANs
-eth1   192.168.0.2, directly connected to the router (A)
-eth0   192.168.2.2, directly connected to the router (B)

The routing with router (A) or (B) work fine.

I want to do a load balancing using teql

I have configured the qdisc and teql as follow

#ip route del default
#tc qdisc add dev eth0 root teql0
#tc qdisc add dev eth1 root teql0
#ip addr del 192.168.0.2 dev eth1
#ip addr del 192.168.2.2 dev eth0

#ip address add 192.168.0.2/24 dev teql0
#ip address add 192.168.2.2/24 dev teql0
#ip link set teql0 up
#ip route add default/0 dev teql0

The rp filter of eth0 and eth1 are turned off by default. After I have done some ping and traceroute but I haven't answers then I have done

#ip neigh ls
