OpenGFW 是一个 Linux 上灵活、易用、开源的 [GFW](https://zh.wikipedia.org/wiki/%E9%98%B2%E7%81%AB%E9%95%BF%E5%9F%8E)
|
|
|
|
|
实现,并且在许多方面比真正的 GFW 更强大。可以部署在家用路由器上的网络主权。

#### 支持的 action
|
|
|
|
|
|
|
|
|
|
- `allow`: 放行连接,不再处理后续的包。
|
2024-01-28 05:27:27 +08:00
|
|
|
|
- `block`: 阻断连接,不再处理后续的包。
|
2024-01-20 08:45:01 +08:00
|
|
|
|
- `drop`: 对于 UDP,丢弃触发规则的包,但继续处理同一流中的后续包。对于 TCP,效果同 `block`。
|
2024-01-22 08:11:01 +08:00
|
|
|
|
- `modify`: 对于 UDP,用指定的修改器修改触发规则的包,然后继续处理同一流中的后续包。对于 TCP,效果同 `allow`。
