I also try to configure the other network interfaces of the penetrator and I notice that the name of the interface in the Network Setup / Other Network Adapters doesn’t matching the physical adapters.

When I clique on the menu  ‘’Other Network Adapter’’ I see ETH1 and have assigned 192.168.5.10 to that interface but when I connect my Ethernet cable to ETH1 I can’t ping the 192.168.5.10 unless I plug the cable in the ETH2. It means that ETH1 in the configuration is equal to ETH2 physical port of the Penetrator. Also when i assigned  an ip address to my PC in the subnet 192.168.4.0 and I plug the Ethernet cable in the ETH1 I successfully ping the 192.168.4.9 that I have assigned to ETH0

It's the operating system that assigns names ethx to physical network
adapters. So, correspondence cannot be guaranteed 100%.
It's possible to reset this assignment in the system console, option 10,
then reboot.
