Hy 🙂

I have a problem with the eth2 (rj45 isolated).

Dhcp mode, it doesn’t get any ip address.  
When i give a static ip address, no link with outside.

All the others ports (lan, sfp) work ☹

I have this error :

are you seeing interrupts happening on the interface. Also random question, have you tried a different ethernet cable?

This is with OpenWRT? What do your firewall rules look like?

Hy 🙂

No, i use a linux based on Buildroot.  
About firewall, no rules in place.  
All the rj45 and thé sfp work.
