|
|
=======
|
|
|
|
[Stunnel][1] is a proxy designed to add TLS encryption functionality to
|
|
existing clients and servers without any changes in the programs' code.
|
|
|
|

bridge:
|
|
image: vimagick/stunnel
|
|
ports:
|
|
- "1194:1194"
|
|
environment:
|
|
- CLIENT=yes
|
|
- SERVICE=openvpn
|
|
- ACCEPT=0.0.0.0:1194
|
|

|
|
extra_hosts:
|
|
- server:1.2.3.4
|
|
restart: always
|
|
```
|
|
|
|
### Server Setup (Cloud)
|
|
|
|
```bash
|
|
# master server (Japan)
|
|
docker-compose up -d master
|
|
```
|
|
|
|
### Client Setup (Cloud)
|
|
|
|
```bash
|
|
# bridge server (China)
|
|
docker-compose up -d bridge
|
|
```
|
|
|
|
### Client Setup (Local)
|
|
|
|
File: /etc/stunnel/stunnel.conf
|
|
|
|
```ini
|
|
foreground = yes
|
|
client = yes
|
|
|
|
[openvpn]
|
|
accept = 127.0.0.1:1194
|
|
connect = 1.2.3.4:4911
|
|
```
|
|
|
|
> Pro Tip: Running stunnel locally is faster.
|
|
|
|
