**Background**I am working on setting up a secure connection from my home computer to an Android application (APK) for work. The Android device hosting the application is located in a remote network, and I need to ensure that all communications are secure and that the connection mimics as if I am locally present within the same network as the APK. Here's the setup and challenges I'm facing:
SetupHome Computer: This is where I initiate connections. It runs necessary tools like Proxifier to handle proxy configurations.VPS (Ubuntu): Acts as a middleman. It forwards traffic from my home computer to the APK and vice versa. The VPS is equipped with WireGuard to establish a VPN connection.APK (Android Application): Hosts the application I need to access. It connects back to the VPS via a WireGuard VPN, ensuring that all data transmitted is secure.
Challenges
Routing Incoming Traffic from Home Computer to APK via VPS: The primary challenge is setting up the network such that all traffic from my home computer is directed to the APK through the VPS. This setup involves configuring IP forwarding and NAT rules on the VPS to correctly route the traffic from my home computer to the APK without any leaks or misrouting.
Ensuring the APK Uses Its Native IP for Internet Connections: For certain application functionalities, it's crucial that the APK accesses the internet using its native IP address and not the IP of the VPS. This setup is needed to ensure that responses from services on the internet see the requests as coming directly from the APK, which is necessary for geolocation services or IP-restricted accesses.Stack Overflow Question
I am trying to achieve a seamless and secure connection setup where my home computer can interact with an Android APK as if I am locally connected within the same network. Here are the specifics I need help with:
How can I configure the routing on the VPS to ensure all traffic from my home computer is forwarded to the APK via WireGuard VPN? I've set up basic IP forwarding and NAT rules but am unsure if I'm covering all necessary aspects.
What settings should I adjust on the APK or the VPS to make sure that while the APK can route traffic coming from my home computer, it still uses its own native IP address for other internet activities? I need the APK to appear with its native IP for all its outgoing connections to the internet.
Any insights or suggestions on how to configure these components effectively would be greatly appreciated.
So far I've set up a network configuration where your home computer routes its internet traffic through a VPS via Proxifier. The VPS is equipped with WireGuard to establish a secure VPN connection to an Android APK, which hosts a specific application you need for work. The main challenges have been configuring the VPS to correctly forward traffic from your home computer to the APK and ensuring the APK uses its native IP address for its own internet activities, rather than the IP address of the VPS. This setup is aimed at enabling secure, seamless connectivity to the APK while maintaining proper internet functionality under the APK's native IP for authenticity and compliance with geolocation or IP-restricted services.
Included are the current IP rules I have enabled - what am I missing?
