Issue
ETCnomad appears to not be usable as a DHCP server, and the DHCP section of the Shell (ECU in Eos, System Settings in Cobalt) is greyed out.
Explanation of Issue
On a PC, ETCnomad for Eos or Cobalt utilizes GCE's (Gateway Configuration Editor) Net3 Services for its Network Address Server. In order for the DHCP server to become active and usable, GCE must be installed on the same PC as ETCnomad Eos or Cobalt.
Additionally, the "Launch Eos Family" application must be started As Administrator to make changes to the DHCP Service.
On a Mac, GCE cannot be installed. This means a third party program or another device must be used as the DHCP server. We apologize for the incovenience.
Mac OS can run a DHCP Server, enabled via Terminal. https://discussions.apple.com/thread/8534373
