State: closed
Merged: No

Describe your changes

When WgPort is configured as 0, the engine picks a random free port at startup (connect.go:598), but GetConfig was reading WgPort straight from the on-disk profile config. The UI therefore showed the default WG port instead of the port WG is actually listening on.

This change adds Engine.GetWgPort() exposing e.config.WgPort (the resolved port), and updates the daemon's GetConfig RPC to fall back to the engine's value when the configured port is 0 and the engine is running. The configured port is still returned when set explicitly or when the engine isn't up.

Summary by CodeRabbit

Bug Fixes
- Enhanced WireGuard port reporting to correctly display the actual port being used, including properly handling cases where the port is dynamically assigned at runtime rather than statically configured.

**Original Pull Request:** https://github.com/netbirdio/netbird/pull/6151 **State:** closed **Merged:** No --- ## Describe your changes When WgPort is configured as 0, the engine picks a random free port at startup ([connect.go:598](https://github.com/netbirdio/netbird/blob/07e5450117dd0451aaeefc18729a822115587e69/client/internal/connect.go#L598)), but `GetConfig` was reading WgPort straight from the on-disk profile config. The UI therefore showed the default WG port instead of the port WG is actually listening on. This change adds `Engine.GetWgPort()` exposing `e.config.WgPort` (the resolved port), and updates the daemon's GetConfig RPC to fall back to the engine's value when the configured port is 0 and the engine is running. The configured port is still returned when set explicitly or when the engine isn't up. ## Issue ticket number and link https://github.com/netbirdio/netbird/issues/4557 ## Stack  ### Checklist - [x] Is it a bug fix - [ ] Is a typo/documentation fix - [ ] Is a feature enhancement - [ ] It is a refactor - [ ] Created tests that fail without the change (if possible) > By submitting this pull request, you confirm that you have read and agree to the terms of the [Contributor License Agreement](https://github.com/netbirdio/netbird/blob/main/CONTRIBUTOR_LICENSE_AGREEMENT.md). ## Documentation Select exactly one: - [ ] I added/updated documentation for this change - [x] Documentation is **not needed** for this change (explain why)  ## Summary by CodeRabbit * **Bug Fixes** * Enhanced WireGuard port reporting to correctly display the actual port being used, including properly handling cases where the port is dynamically assigned at runtime rather than statically configured.
