RE: diffrent way of securing a subnet! Please help

["Jon Pastore" <jpastore () idetech net>]

Need more details...you have a remote office or local? What kind of
bandwidth? Also what are you trying to restrict?

I setup at a clients a Linux box with iptables and 3 subnets: 

1.) 10.2.1.0/24 privileged users
2.) 10.1.1.0/24 non privileged users
3.) 10.1.3.0/24 remote office not privileged

The Linux box acted as a router/firewall (we're also installing a watch
guard box to further protect his stuff...) but this box knew about all 3
networks and how to route to each of them and I just used iptables to
control it...similar to your Cisco solution but there are a ton of tools
out there for configuring iptables and parsing logs etc...also if you're
just trying to manage web traffic you can use squid on this box (Linux
proxy server) and control users like that...

Hello All!
        I need to secure a subnet and restrict access to certain users.
I have been looking at different way to do it and I didn`t find many
real way to do it just some concept. Here the solution I found on the
net:

1- Access-list on the interface of that subnet. Very difficult to
manager and limite allowed user to use a specific workstation or vlan.
2- Cisco Pix firewall. Too expensive not justifiable for the projet
3- Remote access software. Which one is really secure? PCanywhere, VNC,
terminal server
4- Authentication base proxy. Novell borderManager seem to do the job,
squid also seem to do it. Any other that can be link to an active
directory
5- VPN software peer to peer. Microsoft has a solution.

I also read about  role base access control (RBAC) but it seem to be
implemented in the OS not as a stand alone software or in router. Am I
right? Where is the official web page for squid?
