This is useful information, but In the case of a typical (UK) ADSL router,
there is no way to configure the router. It's entirely a black box.
Contractually (with British Telecom), you are not allowed to replace the
box which they supply.

Is there any other way to make a DMZ?

e.g. what about make ISA/RRAS do some NAT on selected IP addresses, create
a 'DMZ' with a private address range (but excluded from the LAT) - e.g.
192.168.254.0/24 ?

What are the security / operationa / other implications?

Thanks

Clive
