Is there a way I can check and see exactly how much bandwidth is being used by a user/computer? The TZ170 show an IP address and the ammount of data they have transmitted, but it does not show what that IP transmitted to or from, nor does it really tell me much about how much bandwith that IP is hogging.  More specifically there are some users that are using internet radio and it is starting to kill our connection. I would like to be able to see that computer x is hogging 64k of data, going to/from x.x.x.x/www.website.com on port xxxx in realtime.  Cost will be a concern.

PS I tried Viewpoint but it did not give me what i was looking for.

There is no specific way to do this as the TZ unit won't show you on a per IP basis. What you can do is increase logging and see what internet radio websites they are accessing then block them.

Also you can use tools like  Ntop (http://www.ntop.org) or Ethereal (http://www.ethereal.com) to get an idea of who's connecting to what.

you need to put a sniffer between your LAN and the gateway. As 0xSaPx0 pointed ntop and ethereal are 2 great tools for that. Ntop if you want long term stats and ethereal for a quick investigation.

You will either need a switch that supports port mirroring, where you will mirror all the ports to one port and sniff on that port, or you can put a HUB in between your LAN and Gateway, and plug the sniffer into the hub as HUBS have all ports in the same collision domain you'll be able to sniff all traffic.

Sonicwall has a subscription service called ViewPoint that actually records this exact info for you.  It is about 99 dollars to subscribe to and you can put the license code in your Sonicwall to unlock the functionality.  Sign in to MySonicwall.com and register your box and you can purchase it right there.  The free services mentioned above work well if you know how to use them.

We had the same exact issue.  I wish I had known you were unable to mount the old .edb and I would have posted this sooner.  We had Microsoft work on this problem and here is what they sent me as thier notes.  They were successful in saving the databases.  It's to late to help you but someone else will hit this eventually.
