Great! That worked.  Thanks.  Now, is there a page I can refer to for
other commands and syntax like adding multiple ports?  I tried the
following and assume it works.

${fwcmd} add 301 deny all from "table(2)" to me 20-25,110,113,143

# ipfw show
00301       0          0 	deny ip from table(2) to me dst-port
20-25,110,113,143
