You could have the Cisco establish your multiple PPPOE sessions over the
various VCIs. This would of course require that the Cisco perform NAT
functionality, but you could do 1:1 NAT with multiple "Server IPs" on
the m0n0 and accomplish what you're looking for. You may have some extra
work to get IPSEC, SIP, etc. going though. I suppose one option if you
do need IPSEC or SIP or some other NAT un-friendly protocol would be to
let the Cisco establish one PPPOE session (eg. For your DMZ) and let
m0n0 get the other.

This link should get you started:

ample09186a0080126dc0.shtml

BTW: Don't let the diagram through you off... The Cisco router IS the
PPPOE client in this example.

Ah. Well, nevermind then. WingNET usually routes a subnet if a customer
needs
multiple IPs. I'd be interested to hear about any resolutions you can
find
to your problem.
