Currently, I have two VPN clients on most of my devices:
- One for connecting to a LAN
- One commercial VPN for privacy reasons
I usually stay connected to the commercial VPN on all my devices, unless I need to access something on that LAN.
This setup has a few drawbacks:
- Most commercial VPN providers have a limit on the number of simulations connected clients
- I either obfuscate my IP or am able to access resources on that LAN, including my Pi-Hole fur custom DNS-based blocking
One possible solution for this would be to route all internet traffic through a VPN client on the router in the LAN and figuring out how to still be able to at least have a port open for the VPN docker container allowing access to the LAN. But then the ability to split tunnel around that would be pretty hard to achieve.
I want to be able to connect to a VPN host container on the LAN, which in turn routes all internet traffic through another VPN client container while allowing LAN traffic, but still be able to split tunnel specific applications on my Android/Linux/iOS devices.
Basically this:
+---------------------+ internet traffic +--------------------+
| | remote LAN traffic | |
| Client |------------------->|VPN Host Container |
| (Android/iOS/Linux) | |in remote LAN |
| | | |
+---------------------+ +--------------------+
| | |
| remote LAN traffic| | internet traffic
split tunneled traffic| |-------- |
| | v
v | +---------------------------+
+---------------------+ v | |
| regular LAN or | +-----------+ | VPN Client Container |
| internet connection | |remote LAN | | connects to commercial VPN|
+---------------------+ +-----------+ | |
| |
+---------------------------+
Any recommendations on how to achieve this, especially considering client apps for Android and iOS with the ability to split tunnel per application?
Update:
~~Got it by following this guide.~~
Ended up modifying this setup to have better control over potential IP leakage
I’ve been toying with this idea but with a mesh network, in my case nebula, after experiencing a similar frustration with limitations on most client devices when trying to connect to multiple VPNs.
One question I’ve been trying to answer is if routing all of these devices to a single vpn endpoint has any negative effects on privacy. Would cycling the IP randomly help to prevent trackers from putting together a profile of activity?
Your browser gives them enough information to profile you by they don’t really need your ip address.
I guess what I'm getting at is now instead of them tracing your activity to one browser or device, they can more easily group multiple devices since they're all using the same VPN IP.
