It might be worth your while to see if you can try to build and test the 1.0 pre-release:

Bertilson,

It's remains the same wiht "-p". Even if this works,
is not what I want,I wanna the whole bandwith,
passing through a single interface.

I'm using the release 0.17.

Thanks!

Any difference in behavior if you use the "-p" (promiscuous) option?

Are you using the previous release (0.17) or 1.0pre2?

Warren,

Sorry for won't be clear;

Lets me try explain better.

As long I open the iftop (passing an interface as parameter)
it's show all traffic passing through the respective
interface; but shortly after, it starts decreasing
the traffic that value, until remains only:
current bandwidth usage by pairs of hosts,
this means, only hosts directy connected
with the current host (the freeBSD).

As this host is a router, most of the  traffic that
pass through it, isn't directy connected
with it, it's just forwards this traffic.

So, as I wanna monitoring whole bandwidth, passing
through the interface, the iftop does not show
it (all the time, just when I start it); just the traffic of
pairs of hosts.

Is possible monitoring all traffic passing through
the interface, instead only the traffic of the
pairs?

Thanks!
