>Description:
this:
ipfw -q add ${rule} count ip from any to ${ip} xmit ${iface} 
ipfw -q add ${rule} count ip from ${ip} to any recv ${iface} 

counts exactly twice of when using via instead of xmit|recv BUT! only for the recv rule. xmit is ok.
>How-To-Repeat:
using rules in description
>Fix:
      none
