the problem is, there is no log entry for the second network card. The strange thing about it: it finds the external network card and if i remove the external unRaid finds the internal card. So they work both - but not at the same time. Maybe unRaid stops to load another network card if it finds one.
I don't really understand what you mean with your ifconfig command. My Problem is i have two routers, so i will need two differnt network cards, or am i wrong?
