If port hopping is required, kindly customize the provided command as per your requirements and execute it accordingly

In the provided command, users are permitted to utilize any port within the range of 20000 to 40000 for connecting to hysteria2, whereas the backend operates on port 40001

Please input "20000-40000" for the client port and "40001" for the backend port in the WHMCS node details

# install iptables-persistent

Please install the V2bX backend using the following command:

wget -N https://raw.githubusercontent.com/theresaarcher/V2bX-script/master/install.sh && bash install.sh

After installation, edit the configuration file /etc/V2bX/config.json as shown below:

{
    "Log": {
        "Level": "error",
        "Output": ""
    },
    "Cores": [
        {
            "Type": "hysteria2",
            "Log": {
                "Level": "error"
            }
        }
    ],
    "Nodes": [
        {
            "Core": "hysteria2",
            "ApiHost": "https://domain.com/modules/addons/v2raysocks_nodes/web_api.php",
            "ApiKey": "123456",
            "NodeID": 87,
            "NodeType": "hysteria2",
            "Hysteria2ConfigPath": "/etc/V2bX/hy2config.yaml",
            "Timeout": 30,
            "ListenIP": "",
            "SendIP": "0.0.0.0",
            "DeviceOnlineMinTraffic": 200,
            "CertConfig": {
                "CertMode": "self",
                "RejectUnknownSni": false,
                "CertDomain": "snidomain.com",
                "CertFile": "/etc/V2bX/fullchain.crt",
                "KeyFile": "/etc/V2bX/private.pem",
                "Email": "v2bx@github.com",
                "Provider": "cloudflare",
                "DNSEnv": {
                    "EnvName": "env1"
                }
            }
        }
    ]
}

Then upload your certificate files fullchain.crt and private.pem to the directory /etc/V2bX/.

After configuration, start the V2bX backend using the following command:

v2bx

To restart or check the service status, use:

v2bx

V2bX will start automatically after the server reboots.

Modify

If you wish to adjust port forwarding rules, edit the rule files located in the following directory:

/etc/iptables

Then reload the rules with:

sudo systemctl restart netfilter-persistent
