无法创建看似简单的 Stunnel 配置
Unable to create seemingly simple stunnel configuration
我有一台工作计算机位于防火墙后面，内部 IP 地址为 192.168.12.13...防火墙将端口 40000 - 40019 映射到此本地计算机上的匹配端口。 （例如 40000 - 40000、40001 - 40001 等...）并且，让我们将外部 ip 定义为 12.34.56.78。
我想设置我的家庭计算机以连接到这台工作计算机。
工作电脑stunnel.config:
[brianserver]
client = no
accept = 127.0.0.1:40020
connect = 192.168.12.13:40000
ciphers = PSK
PSKsecrets = psk1.txt
家用电脑stunnel.config:
[brianclient]
client = yes
accept = 127.0.0.1:40020
connect = 12.34.56.78:40000
PSKsecrets = psk1.txt
我正在使用一个名为"Hercules SETUP utility"的产品在工作机器上收听：
而且，我正在使用 "Hercules SETUP utility" 从家用计算机发起连接：
如您所见，我收到一条连接被拒绝的消息。

注意：“0.0.0.0:40020”行在我启动 Hercules 侦听器后出现。
Accept 告诉 stunnel 在该端口上 listen。 Connect 告诉 stunnel 打开到该端口的连接。您正在让两台计算机都监听 localhost:40020（这是本地环回）并尝试在外部启动连接。您希望您的工作计算机（服务器）在 192.168.12.13:40000 上侦听，然后通过隧道连接到 127.0.0.1 40020，并让您的远程计算机连接到您的 12.34.56.78:40000 地址并在本地侦听 40020（127.0.0.1： 40020）。这会将您家用计算机上的端口 40020 连接到工作计算机上的 40020 端口。
