    I have a Packet Tracer im working on.
    it consist of a router conecting into 4 switches. Each switch hodls up to 4 computers (give or take one).
    I have set up DHCP on a sever, one for each segment. Problem is i dont know how to get it working. I have the ip address and amount allowed set including sebnet, but thee DHCP request always fails.

    Have you configured IP addresses on each interface?

    Packet Tracer is simulation software from Cisco Network Academy.

    You will need to configure the Router to assign DHCP Leases.

    Yeah, it would be an ACL for a DHCP Relay Agent

    I always use static IP's in my lab as the router wouldn't be the DHCP server, it would be a Windows Server or something similar.

    Not got round to ACL's yet using the IOS, but sure it's going to be pretty straight forward.

    Oh and for the OP, just use static IP's until you get to ACL's.

    I think its one of the PT routers. Every thing is one of the PT type.
    At the top i have a router going Fiber optic to to 4 switches witch connects to a DHCP sever and 5 computers each.



    Routers and all the severs have the ips, And the DHCP is turned on, When you click the envelope in the lover right and click to random computers, you get a message saying this is not a working port. Now unless there is something i need to do in order to tell the computer to go to that sever to get the ip address, witch i have been told might be the problem and they were not sure, or i have messed up on something with the DHCP severs Witch i highly doubt.
    Another thing is i plan on adding at least 50 or so computers to test how it all works, so static is out of the question. I have done 150 computers 20 severs and 20 printers with all static ip address, and I'm not doing it again.

    I have gotten the awnseWhen you go into the DHCP on a server and set up a new pool, change the defult gateway on BOTH pools that are there, if this is not done, as well as the starting ip address, it will, not work, sorry for wasting your time



    If you have packet Tracer 5.2
    the saved file is attached
    that is where i was stuck
