When connected to my Box (Orange Pro), and set to DHCP, ,the eth0 port does not get an IPv4 address. ifdown / if up shows DHCPDISCOVER but no DHCPOFFER.
Set in the same way, eth1 and eth2 work fine (two DHCPDISCOVER and after the second DHCPOFFER etc.
When eth0 is connected to a second R5S which has a dhcp server, then it works normally.
What can explain that ? And what can I do to fix it ? Since eth1 and eth2 works fine, the box is not responsible of the problem.
