Tutorial for setting up local IPv6 for Relay server

In some relay servers, IPv6 may not be provided, and you can create a local IPv6 using this method in your tunnels.

Relay server

To create local IPv6, you need to first install the iproute2 service on relay server with the following command.

sudo apt-get install iproute2

After installing the above service, create the tunnel.yaml file in the netplan folder with nano editor.

sudo nano /etc/netplan/tunnel.yaml

Then copy the following code in the file.

network:
   version: 2
   tunnels:
     tunnel98:
       mode: sit
       local: IPv4-RELAY
       remote: IPv4-Main
       addresses:
         - 2001:db9:900::1/64
  • Instead of IPv4-RELAY put your relay server IP and instead of IPv4-MAIN put your main server IP.

  • After making the changes, save the file by pressing the Ctrl+s button and exit the editor by pressing the Ctrl+x button.

  • At the end, apply the changes made in netplan with the following command.

sudo netplan apply

Main server

To create local IPv6 on the main server, you need to install the iproute2 service.

sudo apt-get install iproute2

After installing the above service, create the tunnel.yaml file in the netplan folder with nano editor.

sudo nano /etc/netplan/tunnel.yaml

Then copy the following code into the file.

network:
   version: 2
   tunnels:
     tunnel98:
       mode: sit
       local: IPv4-Main
       remote: IPv4-IRAN
       addresses:
         - 2001:db9:900::2/64
  • Put the relay server IP instead of IPv4-RELAY and put your main server IP instead of IPv4-MAIN.
  • After making changes, save the file by pressing the Ctrl+s button and exit the editor by pressing the `Ctrl+x' button.
  • At the end, apply the changes made in netplan with the following command.
sudo netplan apply
  • The work is finished.

In this method, local IPv6s are as follows.

Your relay server:

2001:db9:900::1

Your main server:

2001:db9:900::2

Connection test

To test the connection, just ping the IPv6 local relay server from your main server:

ping 2001:db9:900::1

Tip!

Please note that if the firewall is on on any of the servers, it is not possible to test through ping and it is necessary to turn off the firewall temporarily. Firewall setup

How to use

You can use Dokodemo-Door or use GOST on your relay server and instead of IP or domain, use the local IPv6 that you created for the main server.

Example Dokodemo-Door:

{
    "inbounds": [
      {
        "listen": "127.0.0.1",
        "port": 62789,
        "protocol": "dokodemo-Door",
        "settings": {
          "address": "127.0.0.1"
        },
        "tag": "api"
      },
      {
        "listen": null,
        "port": 443,
        "protocol": "dokodemo-Door",
        "settings": {
          "address": "2001:db9:900::2",
          "followRedirect": false,
          "network": "tcp,udp",
          "port": 443
        },
        "tag": "inbound-IPv6-local"
      }
    ],
    "outbounds": [
      {
        "protocol": "freedom"
      },
      {
        "protocol": "blackhole",
        "tag": "blocked"
      }
    ]
}

If you pay attention, in the example above, the local IPv6 value created for the main server is placed in the address field, and 443 is entered in the port field, which you can change the port to the tunneled port.
