A partial solution could be your spare desktop acting as a bridge(4) 
using two NICs, and sysutils/darkstat as the monitoring software.

If you can't or don't want to pass traffic back and forth through the 
spare desktop, try port mirroring (Cisco SPAN port/monitor session), 
"ifconfig em1 up monitor", and sysutils/darkstat.

If you mean to filter http and https by url, you will have to use a 
proxy, and acl filtering. I would recommend use an old desktop to do 
this. This will became the bottleneck of your network.

If you just want to know bandwith usage for each IP address on your 
network, you cold do 2 things:
1) Use a port mirror in your router switch port and redirect this 
traffic to a dedicated interface in your freebsd server and log all 
using net-mgmt/ipfm
2) Configure your router to log traffic to your freebsd server using 
netflow, then configure net-mgmt/nfdump to save and show statistics onf 
the server side.

If you decide to use a port mirror and collect all traffic, you can also 
use net/httpry to log all http urls accesed from your network, but it 
will not work with https, you cant see the encrypted url unless you have 
a non transparent proxy.

I hope this helps you.

Saludos, Juan
