A bit of a newbie here, so forgive me if this question is obvious or not clear. I have enabled Windows Remote Desktop on an old home machine that has a TV Tuner card, so I can remotely schedule recordings. I've set a variety of protections on that machine (changed the listening port; machine gets locked down if wrong password is input, etc.). I'd like to set something up on the router, too, which is using Tomato. If I set up the port forwarding (for Remote Desktop), so that the router will only forward inbound remote connections from my work computer and my laptop (using their mac address), is that reasonably secure? I know, for example, that in a wifi setting, it is fairly easy for someone to intercept and spoof a mac address to get around mac address filtering. Can someone do the same on an incoming remote connection to the router via the internet? Or does Windows Remote Desktop encrypt that traffic somehow? If the mac address that is sent in a Remote Desktop session can be intercepted, how likely is it? Would the person trying to intercept it need to know that the particular incoming connection is trying to make a remote connection? Thanks for any answers. I hope the question makes sense.
