I hope I can make this short enough but still be clear. A non-profit org wanted to have a network where users have to log in to gain access to resources. Active Directory?easy choice. Next, they obtained Internet connectivity, but wanted the users to have to log into the network to use the internet.
Here is the setup: There is one switch (SW1) and one Domain controller (DC1). DHCP is running on DC1. There is a wireless access point connected to SW1 so users can log in wirelessly. The problem arises when I?m trying to set it up where users MUST log into the domain to gain access to the Internet. If I plug the DSL router directly into the switch, then a user would be able to simply log in locally to the computer instead of the domain and since he has an IP address, gain access to the Internet. As far as I know, I can?t use ICS in an AD environment. I tried putting another NIC in the DC and connecting the DSL router to it, but there was no way I could get the NICs to talk to one another (they were both the same subnet). This seems like (and probably is) as simple solution, but it is escaping me on how to do this. BTW, the DSL router is running NAT and is on the same subnet with the rest of the devices.
