DHCP clients get wrong DNS after setting up separate PXE boot server
Posted on 2013-07-01
Router: Routerboard 1100hx2
TFTP boot server running in Ubuntu 12.04
I am trying to run FOG imaging solution .32. Everything works fine and I can PXE boot PC's and image PC's but sometimes other PC's on the network pull the wrong DNS, thus disconnecting them from Internet. I guess this comes from running two DHCP servers on the same network. In my previous router DD-WRT this was fixed by adding DNSMasq options. This router is completely different.
I have tried setting the DHCP Server>nextserver to the address of my TFTP server (192.168.0.45). and the serverbootfile to pxelinux.0. I have not added any other settings. Also I have tried setting whatever DNS settings I could find in the configs of 192.168.0.45.
