Hi Adrian,
We set up lot's of Linux box's on Big Pond Direct, here is some help:

This is up to you, however, I would always specify the LAN IP address you
have assigned to the box.
The reason for this is to do with reverse DNS. If you use the
139.130.xxx.xxx address Telstra have given you for you ppp interface,
reverse DNS will never work correctly because Telstra have already assigned
a FQDN to the 139.130.xx.xx address (for example, 139.130.196.172 is
barrie.telstra.net) you can't change that.
This becomes a problem if you register and delegate a domain, say
'mydomain.com' and then specify that you primary mail exchanger, say,
'mail.mydomain.com' has the address 139.130.xxx.xxx given to you be Telstra.
What can happen is that, while the DNS lookup, 'mail.mydomain.com', will
succeed, the *reverse* lookup will fail. This is a problem when the host you
are trying to send mail to has been configured to check that you are who
claim to be by performing a reverse lookup. This will fail and the SMTP host
you are talking to may refuse to talk back to you or accept any of your
mail!!!!!!!!
So, when you are setting up DNS, pick the LAN address you have assigned to
your box, not the WAN address. i.e, it will be a 203.4x.xx.xx (probably)

No, Telstra need your WAN endpoint to be well known and fully resolved at
all times, they assign the name and manage DNS for it (telstra.net)
