 - Creating the SRv6 TUN adapter (`WintunCreateAdapter`) requires an elevated shell; without admin rights it logs "创建虚拟网卡失败" and continues with only the `inLoopBack` interface — links/bridges still work.
 - To disable TUN creation completely (e.g. for non-admin UI/routing testing), set `"enableTUN": false` in `klalb-config.json` or toggle off "启用 TUN 虚拟网卡" in GUI/Web settings.

@@ -72,12 +78,14 @@ Located in `dashboard/`:
 `klalb-config.json` is an array of items discriminated by their `"Type"` field. Adding a new item type requires a `KLALBConfigItem` subclass **plus** new cases in both `KLALBConfigItem.getDefaultJsonDeserializer()` and `getDefaultJsonSerializer()`; unknown types are preserved as `UnknownKLALBConfigItem`. Any Gson instance handling config must register these adapters via `registerToGsonBuilder` (see `KLALBProxySystem`).
 
 Key controller config fields:
-- `openConnections` / `autoConnections`: published vs auto-connect endpoint lists (replaces legacy `LineTable` / `ConnectLineTable`).
+- `externalEndpoints` / `autoConnections`: published vs auto-connect endpoint lists (renamed from `openConnections`, which itself replaced legacy `LineTable`; the old name was a developer naming mistake — these addresses are this node's externally published endpoints, not "connections").
 - `ntpServers`: time server list (replaces `ntpServerTable`).
-- `denyConnectionQuery` / `denyConnectionBroadcast`: query & discovery broadcast safety flags (replaces `denyLineTableQuery` / `denyLineTableBroadcast`).
+- `denyExternalEndpointQuery` / `denyExternalEndpointBroadcast`: safety flags — the query flag hides ONLY the external-endpoint list in full node-info responses (device name/description still answer; Tiny queries are never gated), the broadcast flag disables LAN multicast discovery (renamed from `denyConnectionQuery` / `denyConnectionBroadcast`, which replaced `denyLineTableQuery` / `denyLineTableBroadcast`).
 - `enableTUN`: boolean flag for TUN interface creation (`"TUNName"` configures device name).
 - `webPort`: default `4665`.
 
+Legacy JSON keys are still accepted on load: `KLALBConfigItem.getDefaultJsonDeserializer()` normalizes old key names (`openConnections`/`LineTable`, `denyConnectionQuery`, `denyLineTable*`, ...) before reflective deserialization (manual rewrite because gson-2.1 has no `@SerializedName(alternate=...)`), and `handleConfig` in the web server accepts them too. New saves always write canonical names.
+
 Gson quirks:
 - **gson-2.1 (vendored) is ancient**: its `JSON_ELEMENT` adapter factory only matches exact `JsonElement.class`, NOT subclasses. Calling `gson.toJson(Object)` with a runtime `JsonObject`/`JsonArray` reflectively serializes the internal field as `{"members": {...}}`. `KLALBWebServer.sendJsonResponse` guards against this by using `JsonElement.toString()` for JsonElement instances — keep that guard when adding new response paths. SSE avoids the issue entirely via `JsonObject.toString()`.
 - `/api/config` GET/POST is parsed field-by-field in `KLALBWebServer.handleConfig` (NOT whole-object Gson reflection) because polymorphic fields (`List<InetAddress>`, `List<MultiProtocolSocketAddress>`) break reflective mapping. Keep new config fields in sync there, accepting both legacy and new JSON key names.
