Hi
Assuming that you want to interface the IP67 device as a DHCP Client to an Ethernet Network (as the DHCP Server) that provides Internet access.
To accomplish that you should go to “Setup” and “Network Interfaces” and configure etho as “WAN” with mode set to “DHCP Client” then submit & ‘save & restart’.
Also make sure that in “Administration” and “Access Configuration” that you enable HTTPS via WAN (on port 443) [submit then ‘save & restart’] or you can lock yourself out.
Once that is all configured and working how will you determine the IP address assigned to the IP67 Gateway from the DHCP Server?
Are you able to access the DHCP Server (Router) and query for DHCP Client addresses?
