Rudy wants to know how secure public apartment wifi is if everyone is using the same password? Leo says it's not secure at all. What it means though, is that anyone who knows the password can use the wifi. But it also means that if someone is malicious, they can use hacking tools to gain access to other people's computers and data. That's why Leo says that a VPN is a must for a situation like this. Or at least only surfing to HTTPS websites only, so the traffic is encrypted. Another option is to use a travel router. It's designed to join a public network and provides a barrier like a VPN.
Ken has a number of emails running in Outlook. A few are Gmail. Everything works fine at home, but Gmail thinks he's being hacked and won't let him log in when he uses a hotspot or VPNs. So he has to go outside the VPN to log into Gmail in order to register the IP. And that only works sometimes. Leo says to go into the Outlook settings and make sure you have a proper profile created using GMail's SMTP for those Gmail addresses, along with your login and password. Leo suspects that is where the hiccup lies. Also, turn on two-factor authentication.
David listens to the iHeartRadio App but he doesn't get the ads, which he enjoys. Leo says that ads are either different or disappear on the streaming app because advertisers don't want to pay for them on the streaming service. This can either be because they are cost-prohibitive, or that an international audience is of little benefit to particular advertisers. And the station doesn't want to give them a freebie. So they get edited out. It's just the nature of streaming radio. One way around this could be to use a VPN to mask location.
Nolan wants to know if he can use a VPN to make networks think he's somewhere else. Leo says yes, that's pretty much what the VPN does. Some people use VPNs to stream other countries' video streams for that very reason. VPNs have a client and a server. The client goes on the users' PC, while the server is somewhere else. Users then log into the VPN, and the IP address will be wherever they connect to it. But there is a catch. VPN providers use a pool of IP addresses that they own, and they identify them as VPN addresses.
Gary has two internet services, T-Mobile and Spectrum. One is for work. He wants to be able to hook them up, so if one goes down, the other picks up. But there's a lag when he uses Zoom. Leo says you can do it with Speedify. It's a VPN that does what's called "failover." But it causes that latency because it goes through different servers. Leo does it with his Ubiquity router Edge Router X and two WAN ports. There's zero latency. TPLink also does that, and they make good stuff.
Wallace wants to know if he needs a VPN or can authorities still track his activity and movements. Leo says that using a VPN will mask your activity unless your VPN keeps track of that activity. With a warrant, they would have to provide that data. As for movements, your cellphone has a GPS, and with a simple request (called a PIN Registry), the authorities can access your location at any given time for a fee. But that is changing as courts recognize that it is a violation of privacy and should require a warrant.
Steve wants to know how he can stream on-demand using a satellite receiver. Leo says that using a VPN through a router could work, his whole network would then appear to be in the US. Leo says he can also use a raspberry pi to run in between it and the streamer. He also wants to be sure his wifi network is protected. Leo recommends also getting the Tiny Hardware Firewall. It uses their VPN or TOR to route the signal. However, it may not be fast enough to stream video.
Peter wants to know if he can roll his own VPN using a NAS. Leo says he can create a VPN using any computer. It just needs a VPN server. OpenVPN is one such. WireGuard is the best choice. It's part of Linux already. But if he's thinking of doing it to work, make sure he has permission to do so.
Vino wants to know why people use a VPN. Leo says that a VPN is a virtual private network. It burrows an encrypted tube from a user's computer to the destination. It's very good for Privacy and Security. Especially when on public WiFi. VPNs can also mask physical location, so people don't know where users are. Great if a user wants to watch TV in another country like Great Britain.
What about the incognito mode in a browser? Leo says that private browser mode doesn't mask IP address. So people can still see where the traffic is going to.
