DNS proxy is a type of server you can connect to which spoofs your location, so you can access content which has been restricted in the region you're actually in.

If you have goland installed in your system, simply download packages and run application by:

go get ./...
go run main.go

1. build docker

   docker build -t dns-proxy .

2. create docker container:

   docker run -itd \
     -v /path/to/config.json:/dns-proxy/config.json \
     -p 53:53/udp \
     -p 80:80 \
     -p 443:443 \
     --name=dns dns-proxy

   make sure port 53, 80 and 443 are free for service to listen

• If you're getting error for port 53 that is already in use try:

sudo systemctl stop systemd-resolved

if it didn't work, try

sudo lsof -i :53

then try to stop services listening to port 53(for example sudo systemctl stop dbsmasq)

You create configuration like sample file existing named config.sample.json.

Remember setup domain value as your server IP address so clients resolve the host name with your server address.

sample config file:

{
  "dnsServerHost": "0.0.0.0:53",
  "dnsServers": [
    "8.8.8.8:53"
  ],
  "domains": {
    "test.com": "127.0.0.1"
  },
  "servers": [
    {
      "scheme": "http",
      "host": "0.0.0.0",
      "port": "80"
    },
    {
      "scheme": "https",
      "host": "0.0.0.0",
      "port": "443"
    }
  ]
}

1. dnsServerHost > 0.0.0.0:53: dns server address
2. dnsServers > ["8.8.8.8:53"]: secondary dns servers so be able to resolve all other domains as it supposed to be resolved
3. domains > {domain: your server ip}: remember to set the server IP address which you want to proxy request from. e.g. {"test.com": "192.168.1.6"} test.com is the domain of website which you want to proxy through server and 192.168.1.6 would be IP address of the proxy server.
4. servers: would be proxy servers of service which enables configurations of exposing port and IP address for further configurations like putting nginx as main router of requests.
