    Hi Folks,

    Home PC Windows 7, I'm seeing IP addresses pop up in my Network view...they seem to be mainly from the USA.....how do I stop them ?

    Cheers

    What makes you think they are from the USA?
    Also is you WiFi password protected?

    Good point, they could be using a VPN. I did an IP lookup on the 3 or 4 addresses I could see in my Network view.

    Yes, have my wifi password protected.

    I don't know what you mean by network view, but these IP addresses, may be from web pages, torrents, dropbox etc

    Post up the IP address of your PC and one or two of the miscrients.

    What router are you using?

    Do you have/use a VPN?

    Where are you observing these errant IP addresses?

    Thanks mate, think it's just other users of the VPN....I blocked the IP addresses in my firewall...and they remained...so thinking about it, it's very probably just other users of the VPN connection. I'll test this tonight by rebooting my box and disabling the VPN....

    One of the "hassles" of VPN's (IMHO) is that you ever know what's connected "the other end" of the link. I would be erecting firewall "my" end of the VPN tunnel to ensure that the only traffic admitted on to "my" LAN was stuff that I wanted. Eseentially, deny all by default and admit only what I want/trust.

    I'm not a networking guru by any stretch....but I don't think they could take anything from my machine....unless of course I have folders shared to Everyone....e.g. I have an apple TV, but disable my VPN while streaming, but when connected I wonder if my shares could be accessed...I have RDP disabled...but need to look into masking my machine to others as an extra safeguard...the only way I can think of for others to gain access to my machine is those who know my password I set on my router !

    Without wishing to sound overly alarmist, if your computer/network is "exposed" to something outside your locale, then there's nothing to stop "them" probing you machines to see what then can find/exploit if they are so minded. This is how quite a lot of virues propoagate themselves and data gets stolen. For businesses, it's the sort of risk company network managers lie awake a night worrying about, (we earn our money mitigating such risk.)

    In your typical SOHO environment, there's a firewall built into your router that stops everything on the Internet "getting at" you local network unless you specifically admit it. If you are using a VPN, they tend to "punch through" such firewalls and "join" your LAN to whatever is the other end of the VPN tunnel (there's a few variants on the way the technology works.) That's basically the point of VPN. So you've either got to trust whatever is the other end of your VPN tunnel, or similarly enure that the tunnel endpoint is "firewalled" in a similar way to how you firewall your LAN/computer from the big bad Internet.

    How to go about that depends on where the tunnel endpoint is (in your router or in a PC) the tunnel "type" (there a few paradigms) and the capabilities of your equipment. And your paranoia level of course.
