Disabling Websites and Messenger on WiFi network

[Und3ertak3r]

Hi

I just joined with a startup company and I have been asked to do an assignment that says that I have to block all the messengers and websites the employees may use like, for eg. google talk, msn messenger, yahoo messenger, orkut, facebook, etc.

I searched about google talk and I found a answer which says:



But the problem is I am not able to add the DNS lookups - I dont know how to. I'll explain the network configuration used:

1. The ISP provider has given a broadband line that goes into the modem they provided, the model is Beetel 450BXI - ADSL2 + Router (lets call this Modem X).

2. Modem X has both LAN outputs (no machine is connected to these) and WiFi transmitter (which I have disabled).

3. Modem X is connected to a NETGEAR Router WGR614v9 (lets call this Router Y) via LAN. And Router Y is the one that trasmits the WiFi to all the nodes we have in the office.

4. No machine is connected to Modem X or Router Y through LAN ports - all use WiFi.

Now how can I do the Website and Messenger Blocking for this configuration? Please keep in mind, we cannot connect the machine thru LAN cables as we dont have the infrastructure for these.

I really need help on this. Thanks a lot.

Well for one I would be looking at the Netgear router.. IT should have a web interface that you may be able to do a bit of mucking around..

or do my trick..Between the Modem and the first Switch/router I installed a Smoothwall or IPCOP box.. (or you could go to Cisco PXE..) these are linux based router OS's.. from there I set my rules .. and block the hell out of unwanted services.. set QOS and all that stuff

Seeing as everyone is on WiFi... I hope your sniffing the air for alternate AP's if the users find they can't FB or IM on the work network.. they may go hunting..
