In ipfw one can use the address "me" which means "address of any
interface on this machine." I don't fully understand what you are trying
to do but am guessing "me" or similar will be of help.

Another angle would be to "whois w.x.y.z" as that appears to be
your current IP address. Stripping out the excess this line is of
interest:

NetRange:   w.(x-1).0.0 - w.x.255.255

The above is one of possibly many IP blocks assigned to your ISP.
