The practical appeal of a mesh-capable VPN solution


↺ The practical appeal of a mesh-capable VPN solution


> The traditional way to do a VPN is that your VPN endpoint ('server') is the single point of entry for all traffic from VPN clients. When a VPN client talks to anything on your secured networks, it goes through the endpoint. In what I'm calling a mesh-capable VPN, you can have multiple VPN endpoints, each of them providing access to a different network area or service. Because it's one VPN, you still have a single unified client identity and authentication and a single on/off button for the VPN connection on clients.



Want anonymity? Make a persona not a mystery.


↺ Want anonymity? Make a persona not a mystery.


> That’s a problem if you really want to be anonymous. If you defiantly refuse to say who you are, it can make people angry that you’re upsetting social reciprocity. You know who they are, but they don’t know who you are. It feels rude. An obsessive personality might make it their damn mission to figure out who you are! You don’t want that.


> So for real anonymity, don’t create a mystery. Create a believable persona. Then nobody will wonder.



In a university, people want to use our IPs even for external traffic


↺ In a university, people want to use our IPs even for external traffic


> Universities are not one of those places. In universities, quite often you'll find that people actively need to use your VPN server for all of their traffic, or otherwise things will break in subtle ways. One culprit is the world of academic publishing, or more exactly online electronic access to academic publications. These days, many of these online publications are provided to you directly by the publisher's website. This website decides if you are allowed to access things by seeing if your institution has purchased access, and it often figures out your institution by looking at your IP address. As a result, if a researcher is working from home but wants to read things, their traffic had better be coming from your IP address space.
