allright , I'm coming back here as I pass my all day trying to make it work.
It is very strange how it goes , as I thought I willjust have to make some basic setup and load my previous config file I saved from the PC.
It did not go like I expect.
lan and wan did not get their right names.
an as the opnwall-rack-edition as 3 Ethernet ports , my old 2 Ethernet cards PC config get lost.
so the rules get lost too.
I should have done something wrong. but as it is too late (23h39) I will see that another day.
If anyone as a suggestion, please let me know.
Thanks a lot
Denis
