Is that really what you want?

    # ipfwadm -A -a -P 192.168.117.2 -D 0/0
    ipfwadm: invalid protocol "192.168.117.2" specified
    Try `ipfwadm -h' for more information.

I'll assume that should be `-S'.

Apart from looking at ip-up, I'd suggest you also think about other
ways of doing this, like:

    # ipfwadm -A -a

if you only have the dialup interface, or

    # ipfwadm -A -a -W ppp0

if you just want to do accounting on your PPP connections.
