Split Tunneling & Local Bypass failing on iVPN with GrapheneOS

[binuts]

Bug report

Describe your environment

• Device : Google Pixel 10
• OS name and version : GrapheneOS, build 2026052401
• IVPN app version : 2.13.0

Describe the problem

Steps to reproduce :

Prerequisite : Ensure the VPN connection is disconnected before starting the configuration steps.

• For Split Tunneling :

1. Navigate to iVPN settings and enable the "Split Tunneling" feature.
2. Select a specific application to bypass.
3. Connect the VPN connection.
4. Attempt to verify that the specified application's traffic bypasses the VPN tunnel.

• For Bypass VPN for Local Networks :

1. Navigate to iVPN settings and enable "Bypass VPN for Local Networks".
2. Connect the VPN connection.
3. Connect to a local Wi-Fi network (LAN).
4. For example in my case, use the Sonos application to discover/interact with local peripherals

Observed Results :

General : The functionality for both Split Tunneling and Local Network Bypass does not appear to function as expected.

• Split Tunneling : The traffic for the designated bypass app still seems to be routed through the VPN tunnel.
• Local Network Bypass : When running Sonos, the application fails to discover or communicate with local peripherals, suggesting the LAN traffic is not correctly bypassing the VPN tunnel.

Expected Results :

• Split Tunneling : Traffic for selected applications should pass outside the VPN tunnel.
• Bypass VPN for Local Networks : Local LAN traffic must bypass the VPN tunnel entirely, allowing local network discovery and connection to function normally.
