Blocking messengers

By rajivnarayanan@hotmail ·
I have a project team that has about 50-55 computers. They are in a particular VLAN. This VLAN hosts access net through a proxy. The same set up is replicated to about 14 different projects. Some projects require messengers to work on their desktops while other projects have banned them.
Is it possible to centrally and selectively block all messengers for a particular project and at the same time allow for other projects.

Yes it is possible by setting ACL in proxy server. I have done it on SQUID Proxy.

You can definitely do that with ACLs. Depending on your network & users, we normally recommend a product called Packeteer, which is a Layer-7 bandwidth mgmt appliance.

It allows you to stop/block or limit bandwidth for web appls & sites. You can set policies, allow/disallow/limit, etc globally, per group or even per IP. You can also set date/time restrictions.

The box is most often used for these main functions:
- stop messaging and other peer-peer traffic
- limit bandwidth for non-critical apps (eg streaming media, non-specific surfing)
- reserve bandwidth for critical apps
- provide QoS of VoIP
- reporting & auditing of network use

It's a little bit more controlled way to do it- this specific device has a pre-definted list of application signatures (layer 7) so it catches apps that morph and port-hop. When you set it up, it automatically identifies & classifies all your WAN traffic and puts it in an easy to read format.

I recommend you use WFilter to get these done.

Our company use WFilter to block messengers, block certain websites and block p2p traffic.
