Description
Describe the Bug
Previously opened this as a feature request (https://github.com/orgs/fosrl/discussions/2772), but this a bug rather than a feature request.
When connecting to a Pangolin instance on Windows, either through OLM or the GUI client, a new virtual network connection and registry entry is created on every connection in the following locations:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\NetworkList\Signatures\Unmanaged
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles
Below is a link to the pull request that another project used to solve the issue. Started looking into the solution, and it seems like the solution here will be similar:
https://github.com/netbirdio/netbird/pull/2479
Environment
- OS Type & Version: Windows 11
- Pangolin Version: 0.9.0
- Gerbil Version: N/A
- Traefik Version: N/A
- Newt Version: N/A
- Olm Version: 1.4.4
To Reproduce
Install Pangolin on Windows. Connect to a network. Disconnect and reconnect. New entries will be visible below and the interface will be named something like olm2 or Pangolin2
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\NetworkList\Signatures\Unmanaged
and
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles
Expected Behavior
Install Pangolin on Windows. Connect to a network. Disconnect and reconnect. The interface name should remain the same and new entries should not be created in the registry.
