-### 身份验证
+### 监控
 
-服务端和客户端的 common 配置中的 `token` 参数一致则身份验证通过。
+frps 当启用 Dashboard 后,会默认开启内部的监控,数据存放在内存中,每次重启进程后会清空,监控数据可以通过 dashboard 的地址发送 HTTP 请求获取。
+
+目前还支持 Prometheus 作为可选的监控系统。
+
+#### Prometheus
+
+在 `frps.ini` 中启用 Dashboard,并且设置 `enable_prometheus = true`,则通过 `http://{dashboard_addr}/metrics` 可以获取到 Prometheus 的监控数据。
+
+### 客户端身份验证
+
+目前 frpc 和 frps 之间支持两种身份验证方式,`token` 和 `oidc`。
+
+通过 `frpc.ini` 和 `frps.ini` 中 `[common]` section 的 `authentication_method` 参数配置需要使用的验证方法。
+
+`authenticate_heartbeats = true` 将会在每一个心跳包中附加上鉴权信息。
+
+`authenticate_new_work_conns = true` 将会在每次建立新的工作连接时附加上鉴权信息。
+
+#### Token
+
+当 `authentication_method = token`,将会启用基于 token 的验证方式。
+
+需要在 `frpc.ini` 和 `frps.ini` 的 `[common]` section 中设置相同的 `token`。
+
+#### OIDC
+
+当 `authentication_method = oidc`,将会启用基于 OIDC 的身份验证。
+
+验证流程参考 [Client Credentials Grant](https://tools.ietf.org/html/rfc6749#section-4.4)
+
+启用这一验证方式,配置 `frpc.ini` 和 `frps.ini` 如下:
+
+```ini
+# frps.ini
+[common]
+authentication_method = oidc
+oidc_issuer = https://example-oidc-issuer.com/
+oidc_audience = https://oidc-audience.com/.default
+```
+
+```ini
+[common]
+authentication_method = oidc
+oidc_client_id = 98692467-37de-409a-9fac-bb2585826f18 # Replace with OIDC client ID
+oidc_client_secret = oidc_secret
+oidc_audience = https://oidc-audience.com/.default
+oidc_token_endpoint_url = https://example-oidc-endpoint.com/oauth2/v2.0/token

 按照上述的示例配置后,`web.yourdomain.com` 这个域名下所有以 `/news` 以及 `/about` 作为前缀的 URL 请求都会被转发到 web02,其余的请求会被转发到 web01。
 
+### TCP 端口复用类型
+
+frp 支持将单个端口收到的连接路由到不同的代理,类似 `vhost_http_port` 和 `vhost_https_port`。
+
+目前支持的复用器只有 `httpconnect`。
+
+当在 `frps.ini` 的 `[common]` 中设置 `tcpmux_httpconnect_port`,frps 将会监听在这个端口,接收 HTTP CONNECT 请求。
+
+frps 会根据 HTTP CONNECT 请求中的 host 路由到不同的后端代理。
+
+示例配置如下:
+
+```ini
+# frps.ini
+[common]
+bind_port = 7000
+tcpmux_httpconnect_port = 1337
+```
+
+```ini
+# frpc.ini
+[common]
+server_addr = x.x.x.x
+server_port = 7000
+
+[proxy1]
+type = tcpmux
+multiplexer = httpconnect
+custom_domains = test1
+
+[proxy2]
+type = tcpmux
+multiplexer = httpconnect
+custom_domains = test2
+```
+
+通过上面的配置,frps 如果接收到 HTTP CONNECT 请求内容:
+
+```
+CONNECT test1 HTTP/1.1\r\n\r\n
+```
+
+该连接将会被路由到 proxy1 。
