Hi all, I'm looking for product suggestions of DHCP servers that require authentication from the client before handing out an ip address. It must also be able to use MAC address registration, and I would like to see if there is a way to only allow clients that have been assigned IPs from the DHCP server to be able to leave the local network segment. IE, make it so someone plugging a rogue laptop into the network and assigning a static IP to their machine, would not have access off the local network segment, or out to the internet, even if through network switch configs even....
I am not sure if this is even possible though, because when I utilized a Bell-Atlantic DSL a few years back, they required me to install a client to be able to get an IP from their DHCP server so I could get to the internet (I was unable to circumvent this), but when I switched to a local DSL provider, over the same physical DSL connection, the local provider assigned to me a local ("NAT'd") static IP, and with that I was able to shoot straight to the internet with the proper network settings, thus successfully circumventing the previous provider by not needing to log into a DHCP server. (Only thing I could guess was perhaps I was using a different class B or C network and a different gateway over the same network segment?) So my question is, does anyone have any DHCP server suggestions? Also, any network hints to handle the second part?
