Our organisation has an old D-Link DSL-G604T wireless ADSL router, and I'd like to be able to find out what is using our monthly data quota, because it's higher than expected. Some visitors are given the WiFi password, and when they are with us, the usage seems to go up by 5 or 10 times, sometimes, but I would not expect them to be doing intensive things like video, but maybe they are.
Having logged into the router, and looked through the menus, and looked at the table of contents in the manual
, I'm not sure if there's a feature that could help here. Would it be the "Remote Log" submenu on the "Tools" menu? If so, how can I use that? P64-65 of the manual says:
"Use the Remote Log menu to set up logging to servers or computers that are located outside the LAN or subnet of the Router."
"Select the Log Level from the pull-down menu. The levels available are: Alert, Critical, Debug, Error, Info, Notice, Panic and Warning. Type in the IP address of a receiver for the log message in the Add an IP Address field and click on the Add button. Log message receivers that are added appear listed in the Select a logging destination pull-down menu. These may be used at any time for other types of log messages. To remove a log message receiver from the list, select it and click on the Remove button. Click the Apply button when you have configured the log message receivers. Remember to save the settings to non-volatile memory."
Q1. Would this "Remote Log" feature give me info on amounts of traffic sent to/from each site or IP?
Q2. Where it says "Use the Remote Log menu to set up logging to servers or computers that are located outside the LAN or subnet of the Router", does this mean we can also log the info "inside" the LAN or subnet of the router? How? (This is probably not an option we'll be taking, because I assume it needs a machine to be running all the time the monitoring is happening (?), and we turn all PCs off when not in use, but I'm interested to know how this could work.)
Q3. The instructions above tell me nothing about how to setup the host where I'm logging to. How is this done? (I do have a Linux webhosting plan with an overseas webhost, where I could perhaps log to, depending on the hosting requirements.)
Q4. Alternatively, is there some log of recent sites/traffic stored on the router that we could use? I haven't found one yet.
Q5. Or would this "Remote Log" feature just give the same (not very useful looking) info as currently goes to the "Log" submenu on the "Status" menu (see P73-74 of the manual).
Please number your answers accordingly, for clarity.
