Need something to filter traffic for network

Posted on 2007-04-05

I would like to put a workstation XP/Other with some sort of software on it that allows me to configure it to filter traffic coming into or going out of our network.  Basically to filter out certain web sites, or certain types of protocols.  We are behind a firewall and router, but locally do not have access to them in order to do this.  Hence the idea of putting something between the firewall and switches.  It would be a bonus to perform other functions, filtering spam, etc.

What suggestions are there for doing this?

You don't have access to your firewall or router, as you've said, so you lose a lot of the easiest ways of doing things.  Do you have access to a server that controls the clients?  For instance a 2003 domain with ISA Server?  

If not, take a look at this link for filtering or stopping internet access on one client:

No, we don't have that type of network setup yet.  I'll check the link out.

I'm still interested.  In fact, I am very busy trying to find something for this purpose.  Currently looking at ClarkConnect, Dansguardian, Squid, Smoothwall, on and on.  Very confusing.  Any more ideas?

Take a look at the Sonicwall line of products.  I personally use them in a few instances, and though their support staff is occasionally not up to par, they tend to do a great job.

For what sounds to be your size of business, you may want to look at the TZ170.

I checked Sonicwall out, but they seem somewhat expensive.  We have 9 locations to populate, so that adds up.  I will check the model you listed.  Thanks.

Out of curiosity, if you're doing this for 9 locations, why do you not have access to the firewall and router you're behind?

Because we have a corporate office in another state which manages the firewalls for each location, including others besides ours.
