867VAE-K9 DHCP ack messages not being recieved

Hi all, 

I am just beginning my first homelab and have been trying to setup a Cisco 867VAE-K9 router, specifically I am trying to get DHCP working, so I can setup the switch I have.
prior I had been trying to setup with vlan1, but had swapped to test that wasn't the issue.
So far on the client end, it receives/sends everything but the Acknowledgement message:

I can confirm its not a client side issue, as I have tried a range of different devices, and on the routers side, it is sending ACK messages, Also when I set the client to a static ip, routing works fine.

Hi @ObsessedLime,

Config-wise, everything looks OK to me. Would you be able to complete the following steps please?

  1. Launch a console/SSH session to the router and perform the following commands in privileged exec mode / enable mode
    1. Disconnect PC from Fa0
    2. clear ip dhcp binding *
    3. debug ip dhcp server packet
    4. debug ip dhcp server event
    5. Restart PC
    6. Reconnect cable from PC to the 867 Fa0 port, do this after reboot at some point during BIOS splash screen / system POST

If you are accessing the CLI via SSH/Telnet you may also need to issue terminal monitor from enable mode (privileged exec) as well in order to see the debug output. If you are connected via the console port it is not necessary. Can you paste the output here or in a .txt file please?

Can I just confirm that your client devices are patched directly into FastEthernet0? Finally, you had the same problem when using VLAN 1? Can you post an output of show version too please?

Thanks!
