That could be a bit of a problem.  Since the modem gets the external IP,
your internal systems really don't know what it is.  I don't know of an
easy way for them to determine it either.  Unless, you've got an
external site that will inform the requester of their apparent IP.

That's better than most.

This is completely dependant on the upstream DHCP server.  Some will
allow renewing your lease before it expires.  This can lead to seemingly
static IP assignments.  Others are not so nice.

I prefer setting it up under inetd and restricting it to localhost
connections.  Then using SSH forwarding to connect to it.  This provides
a suitable balance of security and ease of use for me.  However, it is a
little more complex to setup.

There are a few different implementations of it, but they all function
similarly.  You can find an FAQ on it here:
