**访问控制**
- 三种访问方式：**仅授权链接**（默认，最安全）、IP / 网段白名单（可与授权链接叠加），以及全部放通。
-- 邀请链接可以设置链接有效期、可用设备数、授权后可访问时长（1 小时、2 小时、8 小时、当天有效，或直到通道关闭），以及是否需要审批。
+- 邀请链接可以设置链接有效期、可用设备数、授权后可访问时长（30 分钟、1 小时、2 小时、8 小时、当天有效、直到通道关闭，或自定义），以及是否需要审批。
- 需要审批时，App 会弹出系统通知，一键批准或拒绝；访问者的页面会自动刷新结果。
- **计时从首次连接开始**：同事拿到授权后不用急着连，开始用的时候才开始计时。
- 授权到期或被撤销后，**已建立的连接也会立刻断开**；未授权的连接直接被重置（TCP RST）并留下拦截记录。
+- **申请延长**：访问结束后 2 小时内（通道已关闭也可以），同事重新打开原链接点「申请延长」；你在 App、菜单栏或网页面板里选择延长多久即批准，关闭的通道会自动重新开启。你也可以对已授权或刚结束的设备主动延长。
- **通道组**：添加通道时目标是一个列表，每行一台主机、多个端口用逗号隔开（也可以直接粘贴一串 IP），每个地址一个通道，自动分配一段连续端口，并放进同一个通道组。组内地址共用一条邀请链接和同一份授权：同事授权一次即可访问整组，撤销一次全组断开。
**通道生命周期**

@@ -54,10 +54,11 @@ PortRelay turns that into three steps:
**Access control**
- Three access modes: **invite-only** (the default and safest), an IP / CIDR allowlist (which can be combined with invites), and open to all.
-- Each invite link has its own expiry, device limit, access duration once granted (1 h, 2 h, 8 h, until end of day, or until the tunnel closes) and an optional approval step.
+- Each invite link has its own expiry, device limit, access duration once granted (30 min, 1 h, 2 h, 8 h, until end of day, until the tunnel closes, or a custom length) and an optional approval step.
- When approval is required, the app shows a system notification and you approve or deny with one click. The requester's page refreshes on its own.
- **The access clock starts at the first connection**, so a teammate can accept an invite now and use it later.
- When access expires or is revoked, **existing connections are dropped too**. Unauthorized connections are reset (TCP RST) and logged.
+- **Extensions.** Within two hours after access ends (even if the tunnel has been closed), a teammate reopens the original link and clicks 申请延长 (Request extension). You approve it by picking a duration in the app, the menu bar or the web panel, and a closed tunnel reopens on its own. You can also extend a running or just-ended grant yourself.
- **Tunnel groups**: the add-tunnel form takes a list of targets, one host per row with comma-separated ports (a pasted list of IPs is split into rows), creates one tunnel per address on a contiguous block of gateway ports and puts them in one group. A group shares one invite link and one set of grants: a teammate is authorized once for the whole group, and one revoke disconnects them everywhere.
**Tunnel lifecycle**
