+# 基于规则的 Wireguard
+
+假设您的内核支持 Wireguard 并且您已经启用了它. `Table` 选项可以阻止 _wg-quick_ 覆写默认路由.
+
+例如 `wg0.conf`:
+
+```ini
+[Interface]
+PrivateKey = ...
+Address = 172.16.0.1/32
+MTU = ...
+Table = off
+PostUp = ip rule add from 172.16.0.1/32 table 6666
+
+[Peer]
+AllowedIPs = 0.0.0.0/0
+AllowedIPs = ::/0
+PublicKey = ...
+Endpoint = ...
+```
+
+然后在 Clash 中您只需要有一个 DIRECT 策略组, 它包含一个指定的出站接口:
+
+```yaml
+proxy-groups:
+  - name: Wireguard
+    type: select
+    interface-name: wg0
+    proxies:
+      - DIRECT
+rules:
+  - DOMAIN,google.com,Wireguard
+```
+
+这通常比 Clash 自己实现的用户空间 Wireguard 客户端性能更好. Wireguard 在内核中支持.
