 I have a sky router and 12 devices on.  When I scan devices they are set up as file server, upnp and one as a “host”. 
 ports 135.  139.  445. Are open  and  on my sky+ port 8080 is opened as a second web server
i am just wondering if these are all safe?   Any advice would be very welcome.  Thanks

    Are they open externally? If not it's safe.

    Try running a port scan from the GRC Shields Up site:

    You might also want to check the router and make sure that upnp is turned off. This will prevent any internal devices from opening up random ports without your knowledge. You might need to reboot your router after you do this.

    Hi @ComputerDumbo1 Marc’s suggestion to turn off “upnp” will be a good check to prove which functions/software are opening ports but bear in mind that some of your apps may not function correctly, or at all, when upnp is disabled.

    Hello everyone, I was wondering how to stop temporarily a device within my network? It used to ask if you wanted to use that action.

    @CDM69 , I'll start the conversation, though am sure others will chime in as well.  
    • Off the top of my head, and because you are in a Fing Forum, Fingbox is a product that can be used to deny network access to devices on your network and prevent new devices from joining if you so desire.  Its easy to use, has a comprehensive mobile app and really works well.  You can purchase one at Amazon...
    • Many routers support some type of parental control (or blanket blacklisting) which allows you to block devices either permanently, or via custom schedules.  Brands include Asus, Google, Linksys, Eero and a host of others.
