I am still using win7 and Windows Media Center For a Dvr because I prefer Windows Media Center over any other DVR software I have tried (also, not all tv tuner cards are supported in linux). WMC is performing well for me, but I am pretty sure that my win7 PC has become compromised in terms of security and I need to find a way to isolate it from malicious internet traffic or at least from the rest of my local network..
Can your router firmware be used to close ports or narrowly control traffic to specific hosts within a network?
Can your firmware include antivirus, etc to intercept malware at the router, or can it require internet traffic addressed to a specific win7 host to go through a linux host and be scanned by a real time antivirus program that can scan both windows boxes and linux boxes? Cand it close/open specific ports on a host? If so, I should be able to continue limited(dedicated) use of the DVR box safely on my network.
Does anyone know if this is possible?
