error on hanle client: Neither a NATed or SOCKSv5 connection

Hi,

When redirecting traffic through iptables (using DNAT or REDIRECT), moproxy gives the message

[INFO] error on handle client: Neither a NATed or SOCKSv5 connection

However, it successfully passes SOCKS5 curl requests. In the same situation, transocks redirects traffic without issues. What could be the problem? The version I'm using is 0.3.9 or 0.3.12. The maximum version I can use is 0.3.12; versions higher on android 5.1 than this give an error

CANNOT LINK EXECUTABLE: cannot locate symbol "__register_atfork" referenced by "/data/bin/moproxy_0.4.1_linux_aarch64_android.bin"...

Hi there,

So you use iptables on Android? Is transocks also use iptables with DNAT/REDIRECT?

I haven't test it on Android and not sure what may cause it.

Yes, the redirect via transocks works without problems. moproxy in the same mode receives "error on handle client: Neither a NATed or SOCKSv5 connection" :/

ОК :( ...

I'm getting the same message on a MikroTik (arm64, DNAT)
For some reason it enters the socks5 logic

async fn accept_socks5(client: &mut TcpStream) -> io::Result<Destination> {
    // Not a NATed connection, treated as SOCKSv5
    // Parse version
    // TODO: add timeout
    // TODO: use buffered reader
    let ver = client.read_u8().await?;
    if ver != 0x05 {
        return error_invalid_input("Neither a NATed or SOCKSv5 connection");
    }
