TD> I have a fairly restrictive ipfw setup on  a FBSD 8.2-STABLE machine.

TD>    #####
TD>    # Allow icmp
TD>    #####

TD>    ${FWCMD} add allow icmp from any to any

  ${FWCMD} add 1 allow icmp from any to any


TD> It does work but, two questions:

TD> 1) Is there a better way?
TD> 2) Will this cause harm or otherwise expose the server to some vulnerability?
