Client Isolation
Hi all, i have had a request from one of my customers to stop his clients from being able to see each other on the network and only allowing internet traffic, I suggested a layer 2 switch and forward all the network ports to the gigabit port on the switch and feed that to the router, but i found out he has a large wireless network and cabled network. I am thinking about setting him up a PPPOE server and attaching it to the Active Directory, does anyone else have any ideas as that will be alot of messing about setting up PPPOE on all there machines!

Re: Client Isolation
Just block all local IP's on locked down firewalls apart from the gateway/router, with it being active directory I presume you can set a global security policy blocking firewall modifications

Windows firewall and group policy
BTW, my post has totally changed, got hold of the wrong end of the stick first reply.
BTW2, Every switch is at least Layer 2(MAC level), did you mean Layer 3?

Re: Client Isolation
Yes i did mean layer 3 my mistake, the client doesnt use active directory for routing, i use a cisco PIX, i was hoping i could put a linux box in line with the router as im not a windows guy.

You wouldn't use active directory for routing, you'd set the default domain policy to enable the firewalls on the client PC's. You'd then put out a policy via AD that set each firewall to block communication to anything that isn't a server or internet connection.

If you refresh directly after a post then it'll resubmit the post data, best to click on the thread link instead of refresh
