DUND pre-pppd script

Hi,

I need to determine my ppp IP address pair before I run pppd.

The reason is that I have several network interfaces running at once on my
system so I need to choose an IP address in a subnet that is not already
taken.

Would you recommend that I add a pre-ppp-up mechanism to dund to do this?

If someone knows how to get pppd to run a script *before* it reads its
configuration file then I would rather do that instead.

Aras
