Continuing to consider why Cisco would or would not support this
application of PPPoE, think about the market for it. Who would want
the capability to plug the router into a DSL modem and support NAT
access for a LAN behind it?
Not the DSL carriers, who are having significant financial problems
as things stand. xDSL pricing tends to range from (lowest to
highest):
Single modem, ADSL, dynamic address. intended for single client ONLY.
Single router, ADSL
Single router, SDSL. This is what the carriers construe as
"business grade" DSL. Where ADSL's bandwidth is asymmetrical and
optimized for a client going outwards to the Internet, SDSL is more
appropriate for server applications, and is generally more
predictable with multiple devices.
So, who is the market for Cisco implementing this feature? Surely
not the carriers themselves. The carriers, indeed, are getting
smarter and smarter about using statistics and filters to know when
an ADSL subscriber is a single client, a group of clients, or one or
more servers.
Implementing this feature would alienate the DSL providers from
Cisco. Sorry, individuals don't buy enough from Cisco to show up on
its product radar screen. Even SOHO xDSL users aren't a large market.
PPPoE has some legitimate applications, such as open access (although
I have doubts about its scalability). But if I understand what the
original poster wants the router to do, I see no incentive for Cisco
to do it, and indeed incentives for Cisco to prevent it.
