Server

1. Install docker
2. clone this repo
3. $ cp server.json.example server.json
4. User configuration server.json

• modify the key field in server.json to some strong password,
• modify the listen field in server.json, port range is supported, total number of 100 ports looks fine.
• other options refers to kcptun

5. Modify the PORT variable in Makefile to be the same port or port-range in server.json
6. $ make privoxy
7. $ make kcptun-server

Client

1. Install docker

2. clone this repo

3. $ cp client.json.example client.json

4. modify the remoteaddr field in client.json to the server ip with port number/range, key field to the same password as the server.json, other options same as the server.json

5. $ make kcptun-client

Then you got a http proxy (privoxy) on client listening on port 12948(CLIENTPORT in Makefile).

For more information, just check Makefile.

Client (IPv6)

If the client remoteaddr in client.json is a IPv6 address, the format would be like [2001:4860:4860::8888]:19900-19999. Remember the square brackets around the ip address.

But to access this remote IPv6 address, the docker container has to have IPv6 address too, even though the host should have real IPv6 address at the first place.

Edit /etc/docker/daemon.json with

{
  "experimental": true,
  "ip6tables": true
}

And then sudo systemctl restart docker and follow same steps of regular client setup.
