Anyone know of a good free program that works on windows that will show my network traffic like the bandwidth. I would also like to see if I can track packet loss. Currently I have a Pixfirewall 515 on the inside and a perimeter 1720 router.

Thanks,

James

ethereal will capture network traffic and you can calculate your throughput, but bandwidth you would have to already know.

I'm not sure what exactly you're looking for.  If you want to examine packets (individually) then Ethereal is a very populat tool.  It basically reads/sniffs packets and displays them inside the application.
http://www.ethereal.com

If you're simply looking for bandwidth, I know of a small free tool called RxTx.  It's a very simple program but effective - shows data in bits or bytes (you choose) coming in and going out.

If you're looking for something more specific, please post it up and we'll see what we can find.

The PRTG Traffic Grapher will allow you to use 3 sensors for free. This product shows bandwidth graphs over short and long-term periods.

You have to enable SNMP on the PIX. Then configure PRTG.

PIX# config terminal
PIX(config)# snmp-server host inside 192.168.254.10
PIX(config)# snmp-server location OFFICE
PIX(config)# snmp-server contact ADMINISTRATOR
PIX(config)# snmp-server community read
PIX(config)# exit
PIX#wr mem

snmp-server host inside = The PC with PRTG installed.
