I don't know anything about ipfwadm but it would be much easier to use on
of these variables in /etc/ppp/ip-up and then remove the rule in ip-down

#    Arg  Name               Example
#    $1   Interface name     ppp0
#    $2   The tty            ttyS1
#    $3   The link speed     38400
#    $4   Local IP number    12.34.56.78
#    $5   Peer  IP number    12.34.56.99
