无法创建看似简单的通道配置

标签: windows tcp connection stunnel

我有一台正在工作的计算机,该计算机位于内部IP地址为192.168.12.13的防火墙后面...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)。此外,我们将外部ip定义为12.34.56.78。

我想设置家用计算机以连接到该工作计算机。

工作计算机stunnel.config:

[brianserver]
client = no
accept = 127.0.0.1:40020
connect = 192.168.12.13:40000
ciphers = PSK
PSKsecrets = psk1.txt

家用计算机stunnel.config:

[brianclient]
client = yes
accept = 127.0.0.1:40020
connect = 12.34.56.78:40000
PSKsecrets = psk1.txt

我正在使用一种名为“ Hercules SETUP实用程序”的产品在工作机上收听:

而且,我正在使用“ Hercules SETUP实用程序”从家用计算机启动连接:

您可以看到我收到一条连接被拒绝的消息。

家用计算机stunnel.log :(这些消息是在尝试连接时发生的)

此外,psk1.txt具有匹配的内容:

brianskey:a3...6r

此外,在工作计算机上:

C:\Program Files (x86)\stunnel\bin>netstat -ano|findstr 40020
   TCP    0.0.0.0:40020          0.0.0.0:0              LISTENING       71888
   TCP    127.0.0.1:40020        0.0.0.0:0              LISTENING       34728

注意:启动Hercules侦听器后,显示带有“ 0.0.0.0:40020”的行。

Accept告诉通道在该端口上监听。 Connect告诉Stunnel打开与该端口的连接。您让两台计算机都在localhost:40020(这是本地环回)上进行侦听,并尝试从外部启动连接。您希望工作计算机(服务器)侦听192.168.12.13:40000,然后将连接隧道传输到127.0.0.1 40020,并将远程计算机连接到12.34.56.78:40000地址,并在40020(127.0.0.1: 40020)。这样会将您家用计算机上的端口40020传输到工作计算机上的40020端口。
