i tried to use ipfw dummynet as described in manual

---
If a device name is specified instead of a numeric value, as in

                    ipfw pipe 1 config bw tun0

              then the transmit clock is supplied by the specified device. 
At
              the moment only the tun(4) device supports this 
functionality,
              for use in conjunction with ppp(8).

----


got "no if support" error message. what i missed?
