I dont know if its a bug or what, i cant add object to my network objects, it says that mac address i entered is invalid. 50:E5:49:A2:88:9F:D3 i checked it and it is 100% correct and online tools tells me that it is Gigabyte pool address.
All messages i get is "Invalid value for MAC address: 50:E5:49:A2:88:9F:D3." if i try use other, made up address it is ok, but this address seems to be invalid for validating algorithm.
I use Zentyal 3.4.3 with all updates installed.
