DHCP server does not give out IP:s

[Greg555]

Hello,

Im new to cisco packet tracer, and I have a one question. 

Why does not my server give out DHCP adresses to the different networks and what should I do to make it work?

On the router i have:

 - For starters, DHCP is a layer 2 protocol. If it needs to serve different networks, you usually need to specify a helper address pointing to the DHCP server  at the default gateway for those networks.

Hello,

you need to make a few changes (additions are in bold):

Router1

!

interface FastEthernet0/0
ip address 192.168.65.1 255.255.255.0
ip helper-address 192.168.100.2

duplex auto

speed auto

Router8

!

interface FastEthernet1/0
ip address 192.168.55.1 255.255.255.0
ip helper-address 192.168.100.2
duplex auto
speed auto

Switch3

!

interface FastEthernet0/1
switchport mode access
!
interface FastEthernet4/1
switchport mode access

On the DHCP server, Server1, you have the wrong default gateway, it is currently set to 192.168.100.2 and needs to be 192.168.100.1.

Thank you so much, it worked! Now all the PC:s can request dhcp adress.

However, I can't ping the wireless ones with the wired ones :/

Hello,

your Router8 is missing the static route below:

ip route 192.168.65.0 255.255.255.0 192.168.50.1
