Also configure your DHCP implementation to force the Nintendo to always get the same internal IP. I have no idea why but that took the score from C to B. I remember needing other magic but can't remember details, nothing else is obvious from my final configuration. There are no special NAT or redirect rules. I would also like to take a moment to complain about the name of this device. Searching for "network configuration" and "Switch" ... it's simply not helpful. Nintendo's marketing department made life harder for us. -- Aaron B. <aa...@zadzmo.org>
