We're building a new facility, and transfering our existing network equipment and domain over to it. We want to allow guest users access to internet only in the new facility. We've got a Windows 2000 PDC/AD/DHCP environment with a sonicwall 2040 firewall. How can I allow guests out to the internet but not allow them to see or access our domain in any way? The sonicwall currently filters web sites, monitors for intrusions, spyware, etc. Will it do this for users not on the domain? How to isolate the guest environment so that anything they do (viruses, etc.) cannot transfer over to our domain? Ideally, we'd like a complete separate DSL or T1 for them, but that's not in the budget.
