    I have a simple network with 3 routers a switch coming off each, with two end computers coming off each. On one router I created 3 DHCP Pools for the 3 user networks. The hosts on the network directly connected to this router pulls IPs fine. However even after configuring the DHCP relay (using the ip helper-address command on the other router interfaces) the other networks coming off the other routers cannot pull IPs. I am confused as to what I may have done wrong.

    There are no VLANs, ACL's or anything. Any ideas?

    Hi Sceritz, are you able to attach the Packet Tracer Activity file (.pkt) so that I can take a more in depth look at the config?

    I am unable to review the configuration on any of the three routers since they all have user exec / privilege exec passwords configured.

    However, I noticed that hosts PC0 and PC3 both have their IP configuration set to "static". This needs to be changed to "dynamic" so that they are able to retrieve their IP configuration dymanically from the HQ router (DHCP server). All the other hosts are fine and are retrieving their IP configuration dynamically.

    My mistake, the passwords for everything is: Sparky

    Also I must have been really sleepy last night or perhaps it's because I closed and reopened packet tracer, but for some reason the computers that were set to DHCP are now pulling IPs. Very confusing. It didn't work at all last night. However I'm very glad that the DHCP relay command is working as intended! :D

    I'm very excited to be learning the intricacies of administration. Thank you very much!
