Bandwidthd ip addresses

[aaron]

I'm trying to use bandwidthd to keep an eye on my users' traffic, but it's only displaying the ip addresses of the interfaces in the same subnet as my pfsense lan interface.  This means that bandwidthd is reporting the ip addresses of my networking equipment and not of the originating user.  Squid correctly logs the originating computer's ip address and not that of the last hop along the way. Any ideas?
