Helldivers 2 Proxy: Do Not Decide Without Measuring

The network side of Helldivers 2 splits in two. On one side are the persistent components: login, progress saving, matchmaking and campaign state. These are held in central services and run over TCP. On the other side is the in-mission stream; it is real-time, latency sensitive and runs mostly over UDP.

The whole proxy decision rests on this distinction. An intermediary can touch the first group; in most setups it cannot touch the second. Knowing that from the start eliminates the hours spent on the sentence "I wrote the rule but nothing changed".

Below you will find first the distribution of the traffic, then the limit of SOCKS5's UDP path, then how to set up packet loss and latency measurement, and finally the real use case for a proxy in this game.

Which endpoints does the client spread across?

Over a session the client talks to six independent targets: the login and queueing layer, the service holding progress, matchmaking, the real-time in-mission stream, the shop client and patch distribution. Because they all sit behind the same screen, they look like a single connection.

These targets do not share a protocol. The first three and the last two run over TCP; the mission stream is real-time. That difference is the only variable determining the effect of a proxy rule.

At peak times the login and queueing layer becomes a topic of its own. Queue waits are about capacity and have nothing to do with your network path; coming out of another country does not shorten the queue. Making that distinction saves you from trying to solve an unsolvable problem with a proxy.

Another consequence of the targets being independent is this: one can be unreachable while the others work fine. If the shop client opens but the game login does not progress, the problem is not on your network but in that layer. Likewise, matchmaking stalling while a download flows shows the state of the service, not of your rule. Reading a symptom without identifying which target it belongs to is the fastest way to waste hours in the wrong place.

Before you start diagnosing, keep a simple list: which screen opens, which one stalls, and whether others are seeing the error at the same time. In most cases those three answers alone determine whether the problem is on the network side or the service side.

Where does SOCKS5's UDP path get blocked?

An HTTP proxy opens a tunnel for HTTPS destinations, and that tunnel carries TCP. The details of the method are explained in the CONNECT method Because the in-mission stream carries UDP, it never enters that tunnel; however broadly you write the rule, the result does not change.

On the SOCKS5 side there is a path called UDP ASSOCIATE Its operation is set out step by step in SOCKS5 UDP support In practice three conditions must hold at once: the server must support this command, the network in between must allow the associated flow, and the client must be written to use that path. The third condition is almost never met in game clients.

So the realistic expectation is this: in this game a proxy covers login, shop, patch and matchmaking traffic. Moving the mission stream onto an exit is not possible without client support, and attempts to force it usually end with the game not connecting at all. For a protocol comparison, see SOCKS5 proxy page for more details.

One misconception needs closing here too: a tunnel that wraps the entire device and a proxy defined at the application level are not the same thing. The first establishes a separate transport layer and can carry everything, UDP included; the second only takes the connections routed to it. The tool described on this page is the second kind, and its limits follow from that.

When a client has no SOCKS5 field, some users turn to helper software that forces traffic through. When such a layer routes a UDP stream to an exit that cannot carry it, the result is not a loss of speed but a connection that never establishes. Because the symptom appears as "the game cannot connect to the server", the cause is often noticed late.

Where does the proxy actually touch?

The scope is narrow but useful. On corporate or campus networks where the shop client cannot get out, an exit can make the installation and update side work. Writing a rule without understanding which layer the restriction is at is a waste of time; the diagnostic order is listed in access restrictions on corporate networks .

The second legitimate use is network policies that require a fixed exit address. If an organisation requires all outbound traffic to pass through a known address, download and shop traffic can be bound to that address. This is not a performance decision but a management decision.

The third is verification work: seeing how the shop page, campaign announcements or support content look from a different location. None of these concerns the game session and all of it runs through the browser.

What these three scenarios have in common is that the proxy is used as an access and visibility tool, not a performance tool. In none of them is the aim to speed up the game; the aim is either to open a closed path or to determine where the other side will consider your connection to have come from. Setups that keep expectations within that frame work predictably.

• On a restricted network, first determine which layer is blocked.
• If corporate policy requires a fixed address, narrow the scope to the necessary processes only.
• Do verification work in the browser, not in the game client.

Where should you measure packet loss, and how should you read it?

The most common mistake in diagnosing connection problems is reducing different quantities to a single number. Latency describes the length of the path, jitter how much that length fluctuates, and packet loss the proportion of packets that never arrive. The three arise from different causes and call for different remedies.

Start measuring from your own line. If a test to the router shows loss, the problem is inside the house and no exit will repair it. For measuring to a target outside, ping test tool gives a starting point; to put the method in order, the steps in how to test proxy speed can be followed.

Path measurements need a caveat: because intermediate hops can respond at low priority, loss appearing at midpoints is not always real loss. What matters is the proportion of packets reaching the target at the end. Do not draw conclusions without repeating the measurement several times and at different hours.

Wireless is a topic of its own. Neighbouring networks on the same frequency, distance and walls show up in measurements as loss and variability; that is a problem with your room, not your line. If you suspect loss, run the first test over a cable. If the loss disappears on a cable, there is no point fiddling with exit selection.

Finally, name the symptom correctly. Sudden, brief freezes usually come from variability, consistently delayed responses from distance, and intermittently broken movement from loss. Reducing all these complaints to the single word "lag" blurs which measurement you should take and makes diagnosis harder from the start.

The extra hop's share of the latency budget

Total latency is made up of several parts: the distance from you to the exit node, the distance from the exit to the target, the exit node's current load, the cost of encryption and the handshake, and the intermediate hops along the path. When a proxy is added, the number of these items grows, it does not shrink.

The item users underestimate most is the queue at the exit node. As the number of users sharing the same exit grows, response time grows with it, and that effect changes over the day. Looking at a value measured in the morning and deciding for the evening is the most common measurement mistake. Breaking latency into its parts is covered in what proxy latency is covered in detail in the article.

The cost of encryption and the handshake is a small but not negligible item. A session re-established for every new connection markedly increases the total on short-lived requests. On clients that keep a connection open this item falls; on tools that generate many small requests, the difference becomes measurable.

The practical conclusion is clear: in this game a proxy is not used to improve in-game response time. Because the mission stream does not enter the tunnel at all, the effect is indirect; and for the traffic that does enter, the path lengthens and the time grows.
