Thanks so much for the diagram and PC screenshot. Really helpful.
With the current setup, you have both EPIC Ethernet ports on the same subnet going to the same switch.
This will cause all sorts of problems (think of a feedback loop that never ends).
It should be a matter of simply unplugging the ETH1 of each EPIC and not using that port at all.
With ETH1 disconnected, groov Manage Network page will show ‘Disconnected’ and things should start working.
The EPIC ETH0 are in the same network subnet as the PC, so that is good.
All three devices have unique IP addresses, so that’s also good.
Looking back over your pasts posts, you have the gateway in ETH0 of the EPIC set to 192.168.0.254, so that’s good and it matches the gateway on your PC.
The only difference is that the PC has the DNS set for 184.108.40.206 and the EPIC is set to 192.168.0.4. I don’t know what’s on that dot 4 address. It might be your local DNS, it might not. You need to check into that.
Once you have the DNS IP address confirmed and correct in the EPIC, you should be up and running.
