Double DSL

Unanswered Question

I wonder if someone could help me with the following idea.

We want to get a second DSL line next to our current DSL line.

We would like to use the second DSL line for downstream and the current line for upstream.

There are currently two Ethernet interfaces in use and one available.

I thought to connect the new DSL line to the available interface.

For example:

Eth0 --> DSL Downstream

Eth1 --> Inside Lan

Eth2 --> DSL Upstream

Then create an ACL (probably on the inside) which permits downstream to eth0, deny upstream.

Permit upstream to eth2 and deny downstream.

Could anybody tell me if I am right or wrong, maybe with the correct commands?

I appreciate any reaction.

Kind Regards,
