Good Morning all...
    I'm using a ipmasqadm on a system with a dynamic ip address.  I want to
forward all incoming packets to the masq'd system.  From what I see the
following command is used:

        /usr/sbin/ipmasqadm portfw -a -P tcp -L [external IP] [port] -R
[internal IP] [port]

    Now when I look up my local dynamic address and use it in place of the
external IP, the rule seems to work.  What I'm curious about is weather the
portfw module is capable of using the dynamic address from the ISP....
It'd be a pain to have set all my rules everytime my ISP thinks I've been on
to long and drops me off.....  :)

Thanks

Scott
