I have configured multilink, but I have a strange behaviour.
I can surf without any problems, but if I try to download a 
file, it doesn't matter which size, the download freeze at
aproximately 620kb. 


On the provider side, the "ppp multilink" is enabled on
the virtual template interface. 
The radius user entry is enhanced with 
 cisco-avpair = "multilink:max-links=2"

Here a cut of the client config:
 interface FastEthernet0/0

 no ip address
 no ip route-cache cef
 no ip route-cache
 duplex auto

 pppoe enable
 pppoe-client dial-pool-number 1

interface FastEthernet0/1
 description SDSL
 no ip address
 no ip route-cache cef
 no ip route-cache
 duplex auto
 speed auto
 pppoe enable
 pppoe-client dial-pool-number 1

 interface Dialer1

Any ideas ?

Both routers have 12.4(x).
