"remote.autoForwardPorts": false gets ignored

Does this issue occur when all extensions are disabled?: I don’t know. If I disable all extensions, then I would remove “Remote Development” as well and as a consequence I wouldn’t have a dev container and port forwarding is a moot point.

• VS Code Version: 1.71.2 (user setup)
• OS Version: Windows NT x64 10.0.22000

Steps to Reproduce:

1. Use a dev container with no port mapping
2. Start an express.js application listening at port 3000
3. VS Code will forward port automatically even with the following settings in place (user, container, workspace, as well as devcontainer.json):

{
   // Prevent VS Code's automatic port forwarding
   "remote.autoForwardPorts": false,
   "remote.restoreForwardedPorts": false,
}

I’ve tried four places, and yet VS Code keeps auto forwarding ports.

Where do I need to set this, so that VS Code stops auto forwarding ports?

I’m likely to overlook something but I think this behavior is nasty. If port mapping is not correctly configured for a container, I want the environment to fail fast.

@alexr00 I’ll try to find time this weekend to create a repro repo.

Meanwhile I just came across this item, which may potentially be related. https://github.com/microsoft/vscode/issues/156104 As this item has been just release with VS Code version 1.73.0, it is possible that the VS Code behavior I’ve reported here does not longer occur.

I’m still not able to reproduce the issue of a port still getting forwarded when "remote.autoForwardPorts": false,. Do you have a repo you can share with a setup that reproduces the problem for you?
