I'm trying to bridge two network interfaces on Linux OS (Linux router box in network topology). I have weird problems. When I create a bridge and look for what MAC addresses have my bridge learned, everything looks ok, but if I check and ARP table there are some weird things with incomplete HW address resolutions. When trying to build and delete a bridge many times this happened for addresses on one network or the other (not just for the wireless part). Here is my network topology

Do you see this incomplete entry? Why does this happen? I get the same incomplete problem for the 192.168.1.254 address on the "Linux desktop" box. I don't get it. Level 2 is apparently working inside the bridge as I can see all the relevant MAC addresses learned by the bridge. Why the rest of the system doesn't see that?
I would appreciate your help if somebody have a clue what is happening here.
Best regards,
