Bonding with ADSL

Hi there!

I’ve some problems to create a bonding with 1 adsl interface and 1 cablemodem. The cablemodem interface works fine but the DSL is going down when the bonding is activated.

I think this is cauded by DSL’s pppoe connection… If so, is there any other way to create a bonding?

Thanks in advance.

bonding? what do you bond? and for what?
