Thanks, that seems to work, although adding default route is unnecessary as the whole subnet is already in the routing table, so I only need to create a new ARP entry. And when the entry is deleted, I can no longer connect via MAC. Anyway, something is clearly wrong, since there are no problems like that on Linux and OSX.
