If you take netfilter and the other two PCI cards completely out of the equation (ie: unplug the other cards, and set netfilter to default ACCEPT on all chains with no ruleset), can you communicate with the system at all through this card?
I'll check this today. however I'm changing my whole network to RJ tomorrow. many thanks for help. I'll write about test results as soon as I'll make it.
