Hello

I have a Centos 7 version machine and a 8 port unmanaged switch as my isolated network setup.

@george1421 Hello I’ve DM the traffic cap

@george1421 Ok thank you I updated the dhcp config from example 1 and now i’m seeing different results. Can i share a traffic cap?

@george1421 Hello thank you, For the fog setup I let dhcp service to be handled by fog. not sure why the dhcp config is empty.

Can add these details to the from the 2 screenshots to the dhcp config file?

@Tom-Elliott Ok, but the dhcpd.conf file is empty, where should add those details?

@Tom-Elliott
Hello, Yes you are right it was not but now it is but now stuck here.

@george1421 I’ve disabled the firewall on the server and I’m seeing the same results (only DHCP discover packets going through)

@george1421

I sent over the Wireshark traffic cap over DM, also some screenshots.

@george1421

Ok, here are the results

@george1421 said in Isolated Network Setup (Stuck in Start PXE over IPv4):

Is 192.168.107.x an isolated network?
Yes, its isolated

Is there an existing dhcp server on this subnet?
No, Fog will be it

What error are you getting on the client computer?
Machines are not getting pass the Start PXE over IPv4 screen

I have a CentOS 7 server running FOG and I setup FOG to handle DCHP but i can’t get the machines to boot up over PXE

Network setup:

1 - Wired interface - FOG server machine
1 - 8 port unmanaged network switch
