I have been doing some more reading on this and I believe I have found
something useful but I would appreciate someone's feedback on this:

http://www.debian.org/doc/manuals/reference/ch-gateway.en.html#s-net-reconf 
<quote>However, suppose your computer is a laptop that you transport
between home and work. When you connect the computer to the corporate
network or to your home LAN you need to configure eth0
accordingly.</quote>

Could I use something like this?
--- /etc/network/interfaces ---
auto lo eth0

iface lo inet loopback

iface lan inet static
        address 192.168.0.123
        netmask 255.255.255.0
     
iface wan inet dhcp
--- EOF ---

Other sections of
http://www.debian.org/doc/manuals/reference/ch-gateway.en.html talk
about using mapping to automatically determine which logical interface
should be brought up but I haven't been able to figure that out. 
Firstly I would like to see if the above makes sense to somebody on this
list who knows more about this stuff than I do.

One thing that concerns me about the above is the impact this will have
on the pppd configuration.  I still haven't found out whether 'pon'
needs the 'iface eth0 inet dhcp' line that is in /etc/network/interfaces
on my system at the moment.

TIA for any feedback, suggestions, tips...
