[K12OSN] DHCP on a different port..... was 'The Dreaded DHCP.....'

The whole point of his theory was that he wanted a single NIC setup.

It works fine, nothing to be scared of.

there's no way the MS clients will get an address from a Linux DHCP 
server configured for a port other than 67/68

And the thin clients won't get a response from the MS server.
