Honkai: Star Rail and Proxies: Which Traffic Enters the Tunnel?

When Honkai: Star Rail opens, it does not establish a single connection. The launcher asks for version information and, if necessary, pulls files on the scale of gigabytes; the account layer generates short, frequent requests; and the game session is a long-lived channel that talks to the server for as long as it stays open. The network behaviour of these three is nothing alike.

A proxy does not automatically cover this whole picture. The scope of the rule you write depends on which layer you put it on and on whether the client reads that layer. The account page opened in a browser may enter the tunnel while the game's own socket leaves over your usual line; no warning appears on screen to tell you so.

The third point concerns expectations: a proxy is not an accelerator, it adds a hop. The sections below cover separately what that hop adds to round-trip time, what each measurement tells you, and which symptoms have nothing to do with the proxy.

When does the network speak in a turn-based game?

Because combat is turn-based, the client does not behave like an action game reporting every tile of movement to the server. The request sent the moment you decide, the result the server returns and the interface update all complete within a single round trip. A latency difference of a few tens of milliseconds is therefore usually unnoticeable in gameplay; what is noticeable is the connection dropping entirely or a request going unanswered.

On the other hand, the game runs a verification chain at every launch: the launcher compares versions, the account layer refreshes the session, and then the game connects to its own gateway. If any link in this chain falls outside the tunnel, the symptom usually appears not as "the game won't open" but as "it's stuck on the login screen". The user assumes a server outage; in fact the scope of the rule is incomplete.

The fourth and fifth layers are in the background: event and code pages that run over the web open in the browser, while telemetry and error reporting send small packets without you noticing. Whether or not these two are routed does not affect gameplay, but it muddies the picture when you are verifying where traffic leaves from: an IP lookup you run from the browser shows the browser's egress, not the game's.

What does the added hop contribute to round-trip time?

When you use a proxy, packets do not go straight to the destination: they reach the proxy server first, are forwarded from there to the destination, and the response returns by the same path. The total time therefore consists of three parts — the distance between you and the proxy, the distance between the proxy and the game server, and the current load on the proxy machine. The sum of the three cannot be less than a direct connection; the normal outcome is increased latency.

How much it increases depends on geography. If your egress sits on the path between you and the game server, the added cost is relatively small. If the egress is in the opposite direction — for example, chosen in North America while connecting to an Asian server — packets cross an extra ocean in both directions and the difference becomes noticeable in gameplay. Location choice is therefore a decision that comes before type choice.

The single exception to the rule is this: if your default route is circuitous and the proxy provider's backbone connects more directly to the destination, the extra hop can produce a net gain. This is not a promise but an exception that cannot be assumed without measurement and must be verified. To know which number tells you what before measuring, see the definition of proxy latency and ping expectations in games article.

The practical method is simple: take measurements to the same destination with the proxy off and on, repeat the measurement at different times of day, and place the two results side by side. Ping test gives a one-off snapshot; a decision needs at least several snapshots, because on shared egress the peak-hour difference is the variable a single measurement hides.

Packet loss or latency? Telling the two apart

Players describe two different problems with the same word. Latency is the time it takes a packet to arrive; packet loss is the packet never arriving at all. Their symptoms differ: with high latency everything is late but progresses steadily, whereas with loss the interface freezes for a moment and then jumps to catch up. Loss can ruin the gameplay experience even while average latency looks low.

To read measurements correctly, assess three numbers together: average latency, latency variation (jitter) and loss rate. If the average is good but variation is high, the problem is usually in the line itself or in the congestion of a shared egress. If there is loss, you first need to find where the loss begins; drawing conclusions from the average figure is misleading.

The order of diagnosis is set up like this: first measure with the proxy off. If the loss is present with the proxy off as well, the source is your home line, your wireless connection or your provider's backbone; in that case turning on a proxy does not hide the problem, it adds another layer on top of it. If the loss appears only with the proxy on, change the egress and repeat the same measurement; the problem may be on a single egress machine. For liveness and response testing, proxy checker tool is the first step.

The practical limits of SOCKS5 UDP relaying

An HTTP proxy carries HTTPS traffic by tunnelling it with the CONNECT method, and that tunnel carries only TCP. Because a significant part of game traffic uses UDP, a classic HTTP proxy cannot carry the game's real-time channel. This is not a configuration gap but the definition of the protocol.

SOCKS5 differs at this point: the standard defines a method called UDP ASSOCIATE and allows UDP datagrams to be relayed through the proxy. However, two conditions must be met together. First, the proxy server must actually support this method; many setups permit TCP binding only. Second, the client must know how to use it — most game clients open their own socket and never read the system SOCKS5 setting.

When these two conditions are not met together, the result is silent: the application throws no error, and the UDP packets leave over your usual line without entering the tunnel. In practice this means the account page, launcher and patch download go through the tunnel while the game's own session does not. Users who want to widen the scope therefore mostly turn to application-based routing or a device-level tunnel. For details on the UDP side of the protocol, the SOCKS5 UDP support article goes into depth; for a general comparison, SOCKS5 proxy page for more details.
