My setup is a modem running in bridge mode into to an 8 port switch. I have a router but am interested in trying out a computer as a DHCP server instead. Does the computer acting as a DHCP server have to be connected directly to the modem? Or can the hierarchy go: Modem >> 8 Port Switch >> DHCP Server >> 8 Port Switch (Through same network card) >> Network
Again I am completely new to this, it seems like I would have to have two network cards on my DHCP server computer and connect it directly to the modem and then to the 8 port switch. For the sake of time I'd rather not install the second network card which is why this question arose.
Finally, I have a web server connected to the 8 port switch. If the DHCP server comes first, how can I forward the necessary ports to my internal web server? Is there a type of software that allows me to do this or does it come with the DHCP server. (The computer runs ubuntu linux.)
Thanks for your input!
