Restriction through Network Switch

November 2, 2011 at 11:19:11
Specs: Windows XP/Linux, Intel Dual Core/1GB
I am using a network switch to share my broadband between four PCs.
Among these PCs, one is for students. Is it possible that I can do the following 2 things from modem whose page can be accessed through 192.168.1.1;
1. Restrict some website like Facebook, Youtube etc
2. Limit download speed of that PC to 100KB/s
Regards

not through a switch, no

The only restrictions on switches really is vlan. Essentially you can set your students pc's on one vlan and everyone else on another so they can't talk to each other.

Your going to need to feed your internet through a server of some type to do what your asking. We run Untangle to do what your asking.

Some routers can do this too through

You don't mention what model switch you have but to do vlans you need a managed switch.

You do understand vlans have no effect on facebook etc?

Answers are only as good as the information you provide.

A modem isn't going to filter traffic

Modem's is for converting signal from ethernet to cable/fiber/t1/etc

Switches are not going to do what you want, I already explained what vlan's do and that they will not work

You are going to have to filter your traffic through a server or a router with software on it that can do what you are asking

You'll need to research what software or OS you will be using to do what you want

Servers are not cheap either. Since you are using 4 PC's, a simple home router can block the sites and limit activity times.

www.opendns.com is a great site to use for web filtering. Just point your router to their DNS servers

However, limiting download speed requires some sort of packet shaper.

We have a building with ~100 computers (not counting wireless clients), 3 web servers, an Untangle server and 6 internal servers.

Our untangle allows us to packet shape for certain computers (ie allows me to set speed for certain computers), web filtering, virus protection, spam protection, firewall, web cache, etc. But realize, this solution is expensive. Our server running this costs ~$6,000 plus subscription fee for untangle.

Since you only have 4 computers, I would not worry about packet shaping/throttling and use one of the first 2 solutions for web filtering. My opinion is to use OpenDNS
