choose a network interface to bind

[bart3nder]

Hi!
Is there an option to choose a network interface to bind in our configs (Vmess/Vless/Trojan)? Like the way we do in shadowsocks with -i flag e.g. ss-server -c config.json -i eth9, which pass the traffic through an specified interface.

I have similar question: How the V2ray config file should look like so i can use/bind VPN tunnel (Wireguard) located at interface 10.2.0.2 as my web browser socks proxy? (for example setting particular browser/app to proxy 127.0.0.1:1081 requests will go through the network interface 10.2.0.2)
I have found:
https://guide.v2fly.org/en_US/basics/routing/basics_routing.html
https://www.v2ray.com/en/configuration/protocols/socks.html
But really can not understand how to use it. Any example please?

maybe use "sendthrough" can meet your request

I have tried to replace 0.0.0.0 by 10.2.0.2 but that does not work. How the config.json file should look like please so it does what is described in my previous post or in OP post?

You can use bindToDevice setting for SocketSettings.

Can you show the example full config file please?

Here is a simple config written in JsonV5.

{
    "outbounds": [
        {
            "protocol": "freedom",
            "streamSettings": {
                "socketSettings": {
                    "bindToDevice": "eth0"
                }
            }
        }
    ]
}

Which IP and port i will set in my app (for example web browser) so it uses this "outbounds" and utilize the device mentioned in your config for its network traffic? I already have working and used socks /etc/v2ray/config.json, so i will just append your lines to it please?

Here is a simple config written in JsonV5.

It is named sockopt now, not socketSettings:

{
  "outbounds": [
    {
      "protocol": "freedom",
      "streamSettings": {
        "sockopt": {
          "bindToDevice": "eth0"
        }
      }
    }
  ]
}
