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.
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.
