Can I use a domain name instead of an IP in proxyEndpoint?

[Lalit-Patil-07]

Hi there,

Thanks for the great project!

I have a question regarding the client configuration. Specifically, can the proxyEndpoint accept a domain name instead of a raw IP address?

For example, would this work correctly?

"proxyEndpoint": "testserver.com:8596"

Or is it required to use something like:

"proxyEndpoint": "13.15.18.185:8596"

Here are the full configurations I’m working with:

---

Client_Config.json

{
    "clients": [
        {
            "name": "client",
            "wgListen": "127.0.0.1:7485",
            "wgFwmark": 0,
            "proxyEndpoint": "testserver.com:8596",
            "proxyMode": "zero-overhead",
            "proxyPSK": "sAe5RvzLJ3Q0Ll88QRM1N01dYk83Q4y0rXMP1i4rDmI=",
            "proxyFwmark": 0,
            "mtu": 1500
        }
    ]
}

---

Server_Config.json

{
    "servers": [
        {
            "name": "server",
            "proxyListen": ":8596",
            "proxyMode": "zero-overhead",
            "proxyPSK": "sAe5RvzLJ3Q0Ll88QRM1N01dYk83Q4y0rXMP1i4rDmI=",
            "proxyFwmark": 0,
            "wgEndpoint": "127.0.0.1:51820",
            "wgFwmark": 0,
            "mtu": 1500
        }
    ]
}

Would appreciate any clarification—thanks in advance!

Yes, domain name endpoints are supported, and resolved at session establishment time.

If you have doubts about your configuration, you can start the program with -testConf to check your configuration. It does not check for invalid listening addresses, but everything else is covered.

You can but @database64128 probably doesn't know about the issues you are going to have if you use domain instead of an ip, to make sure domains get resolved you have to use AllowedIPs = 0.0.0.0/1, 128.0.0.0/1 otherwise your wg might have issues in resolving them.
