Metin2 Proxy: Patch Server, Game Session and Account Panel
Your Metin2 setup does not behave like a single line on the network: the updater downloads files, the game client holds a long-lived connection, and account and store operations run in the browser. This page explains how these three kinds of traffic diverge with a proxy, where SOCKS5's UDP side ends, and what happens on the account side when the exit address changes.

Because Metin2 is an MMORPG whose client is installed on your computer, its network behaviour is unlike that of browser-based platforms. The moment you launch the game, three independent jobs begin: the updater checks the file list, the game client establishes a session with the login and world servers, and account operations take place in a separate web interface. When you define a proxy, these three do not have to fall within the scope of the same rule.
The practical upshot is this: you can change your exit address in the browser and open the account panel from a different country, but the game client may still be establishing its own direct connection. Saying "the proxy is working" without verifying the setup often means only seeing that the browser has been routed.
Let the third point be clear from the start: a proxy does not change your account, only which door your traffic leaves by. Your character, registered e-mail and session details stay the same; the only thing that changes on the server side is the address the connection comes from.
How many separate targets does the Metin2 client talk to on the network?
The first part to run is the updater. It fetches the version information and the file list, then downloads missing or changed archives. This traffic behaves like an ordinary file download and generally comes over HTTP or HTTPS; that is, the kind an HTTP proxy can naturally carry. It is also the heaviest step in terms of volume: a version jump can pull down hundreds of megabytes of archives.
The second part is the game client itself. After login verification comes character selection and then a long-lived session with the world server. This session carries short but continuous messages: position updates, combat events, chat lines. The amount of data transferred is small next to a patch download, but keeping the connection from dropping matters more than download speed. A one-second interruption in the session goes unnoticed in a file download but shows up as a disconnect in the game.
The third is the web side: the account panel, password changes, character details and store pages. These are entirely browser traffic, so every setting you define in the browser applies here. The point at which most users say "I've set up a proxy" is in fact only this third layer.
Note
A game client is not obliged to read the operating system's proxy setting. The browser and system setting often affect only web libraries; the client's own socket code may continue exiting directly. Do not assume the scope without measuring it.

A single installation talks to three separate targets. Whichever one your proxy rule covers, only that branch is routed.
What is SOCKS5's UDP side good for in this game?
SOCKS5 has two modes of operation. CONNECT establishes a TCP connection with; that is enough for everything carried over TCP, including the game session. UDP ASSOCIATE is a separate mechanism: the client first opens a TCP control connection with the proxy, the proxy responds with a relay address, and the client sends its UDP packets to that address wrapped in a SOCKS header. When the control connection closes, the relay goes down too.
This flow, which looks clean on paper, gets stuck in three places in practice. The first is the provider side: many SOCKS5 exits allow TCP only and reject the UDP ASSOCIATE request. The second is the client side: an application supporting SOCKS5 does not mean it also supports UDP mode. The third is NAT; if the relay address the proxy reports is not reachable from your network, the connection silently fails to work.
For Metin2 specifically the picture is this: the game session itself runs predominantly over TCP, so UDP support is not decisive in whether the game works. Where UDP becomes important is in the side applications you use alongside the game — voice chat clients, for example. That is why the answer to "is UDP essential when buying SOCKS5?" is given by looking at the tools around the game rather than the game itself.
The decision rule is simple: if only the game and the web panel will be routed, TCP is enough. If voice chat will go through the same exit too, ask your provider explicitly about UDP support and test it before you buy. For details see SOCKS5 proxy, for the mechanism see SOCKS5 UDP support, and for the version difference see difference between SOCKS4 and SOCKS5.
Patch archives, CDN node and update time
In a Metin2 setup, almost all of the data cost comes from the updater. The initial installation and major version transitions pull down a serious amount of volume in one go; by contrast, a daily play session carries incomparably less data even over several hours. If you use a residential or mobile exit billed by data transferred, downloading the patch through the proxy can consume most of your allowance in a single move.
The second variable is which distribution node you connect to. The download is usually served from a content delivery network, and which node you are given depends on who resolves the domain name. If you resolve the domain on your own network, a node near you is returned but the connection is established from the country where the proxy is; the route gets needlessly long. If the proxy resolves the domain (the socks5h form in SOCKS5), the node is also chosen close to the proxy and the path stays consistent. For the distinction where DNS is resolved in SOCKS5.

The practical approach is to separate the two jobs: download the patch over your normal connection and run the game and account operations through the proxy. If you want a rough advance estimate of your allowance, the bandwidth calculation article provides a framework for monthly planning.
What happens on the account side when the exit address changes?
Account panels may request additional verification on a login coming from an unusual location. This is not a punishment but a protection mechanism: the system asks through another channel whether the party who knows the password really is the account owner. Encountering this screen when you start using a proxy is an expected outcome and is usually a one-off.
The real risk here is not technical but a lack of preparation. If you change your exit country without setting up two-factor authentication, the verification channel the system offers you will most often be your registered e-mail address. If your access to that e-mail account is weak or its password is the same, you can end up locked out of your own account. The correct order is this: set up two-factor authentication first, update your recovery details, then change the exit.
The second rule is consistency. The same account appearing from distant countries at short intervals is a picture that triggers re-verification every time. Choose a single fixed exit for an account and stick to it; rotating pools that change the address on every request are designed for open data reading jobs, not for scenarios that carry a session.
Enable two-factor authentication before you change the exit.
Keep your recovery e-mail's password different from your account password.
Use a single, fixed exit for one account; note the sticky duration.
Do not share your proxy credentials in in-game chat or on forums.
Choose an exit country consistent with the account's usual country of use.

There are three definition points, and each works at a different breadth. The operating system setting gives the widest scope: every application that reads the system proxy is affected. A browser profile or extension covers only that profile; it does not disrupt your daily work but does nothing for the game client. Per-application routing targets the process you select and is the most reliable path for game clients.
On the Windows side, the Windows proxy settings article explains step by step where to apply the system setting. But do not be surprised if nothing changes when you enable the system setting and launch the game: if the client opens its own socket, that setting is invisible to it. In that case you need a per-process routing tool or a wrapper that supports SOCKS5.
The format of the connection details is the same everywhere: server name proxy.example.com, port 8080, username username, password password. The real values sit in your provider panel and are not shared. Some providers use IP authorisation instead of a password; this method is practical on connections with a static IP, but in a home with a dynamic IP it cuts off your access every time the line renews. A comparison of the two methods authentication methods the article.
A practical rule for protocol choice: for the web panel an HTTP proxy is more than enough, while for the game client SOCKS5 is more flexible because it does not interpret the protocol it carries. If you will use the same exit for both jobs, choosing a package that supports SOCKS5 saves you from needing a second subscription.
What should you verify once the setup is finished?
Defining a proxy and traffic actually going through the proxy are not the same thing. The verification list is short, but skipping it is costly. First comes domain name resolution: if the browser or client resolves the domain with your local DNS server instead of the proxy, where you connect remains visible to your internet service provider. DNS leak test measures this.
The second is a browser-specific leak. The WebRTC interface can expose your real local and public addresses to a web page regardless of your proxy setting; it does not concern the game client, but it matters if you use the account panel from the browser. WebRTC leak test shows the result with a single click.
The third is IPv6 bypass. If your exit speaks IPv4 only but IPv6 is enabled on your device, a request to a target reachable over IPv6 can bypass the proxy entirely; operating systems prefer IPv6 in most setups. The solution is either an IPv6-capable exit or to disable IPv6 on that profile.
The final step is to measure the exit itself. Anonymity test reports whether the proxy adds extra headers; since an address being defined in the panel does not mean it is alive, verify the exit itself separately as well. Run the tests with the proxy on and off and compare the two results; a single measurement does not show what changed.

Each node represents a separate scope; the result cannot be interpreted without knowing which node you routed.
Latency, continuity and the shared network scenario
A proxy adds an extra hop to your connection. The request first goes to the proxy server, from there reaches the game server, and the response returns along the same path. That is why using a proxy increases latency in most setups; it does not lower your ping. The only exception is the rare case where your default route is needlessly indirect and the proxy sits on a more direct backbone — that is not a rule and cannot be assumed without measurement. The components proxy latency article.
For an MMORPG player, variability matters more than absolute latency. A line with a good average that occasionally spikes is more disruptive than a steady, slightly higher one. In shared pools these spikes become pronounced in the evening hours; that is why, before putting an exit to work, repeat the ping test at different times of day and take the worst result as your baseline.
A continuous connection raises a second limit: the concurrent connection limit. The game client holds a single long session, but if the browser and the updater on the same machine also use the same exit, the total number of connections rises faster than you think. When the limit fills up, the symptom is not an "error" but a silent drop. What the limit means is explained in the concurrent connection limit article.
On shared networks — in an internet café or a dormitory connection, for example — there is one more layer: the network's own filter. In such an environment, the right thing to do before defining a proxy is to learn the network administrator's rules; asking about the permitted exit routes rather than trying to circumvent institutional policy both produces faster results and keeps you out of trouble.

Most of the items in the table are scope problems: if one thing works and another does not, first check which process is being routed. 407 is almost always related to authentication, and it has two sources — either the client is not sending the credentials at all, or the provider recognises you by IP and your home address has changed.
After all this, one more question needs asking: is a proxy really necessary? If you open an ordinary game session from your own country with a single account, putting a hop in between gains you nothing; you only add latency, cost and diagnostic difficulty. The cases where a proxy becomes meaningful are different: verifying how a server list or store page looks in another region, working with a fixed exit address, or consolidating access at a single point in a setup managed by several people. For the general framework of the genre, take a look at the article on using proxies in MMORPGs.
Frequently asked questions about Metin2 and proxies
01Does the Metin2 client use the system proxy setting?
There is no guarantee. The system setting primarily affects processes that use web libraries; a game client that opens its own socket may not see it. The web panel opening through the proxy while the game connects directly is the typical sign of this. The solution is per-process routing or a wrapper that supports SOCKS5.
02Should I download the patch through the proxy as well?
In most cases there is no need. Updater traffic is the bulkiest part of the setup and quickly eats up your allowance on a package billed by data transferred. Downloading the patch over your normal connection and running the game and account operations through the proxy is a practical split.
03Should I ask about UDP support before buying SOCKS5?
If only the game and the web panel will be routed, TCP is enough. If you will also send side applications that use UDP, such as voice chat, through the same exit, UDP ASSOCIATE ask about support before you buy and test it on a trial; many exits carry TCP only.
04Why does the account panel ask for an e-mail code when I use a proxy?
Because it sees the login coming from an unusual location, an additional verification step kicks in. This is expected behaviour and usually happens once. If it repeats on every session, your exit address is changing constantly; switching to a fixed exit removes the repetition.
05The game drops frequently — could the proxy be the cause?
It could be. There are two common causes: the sticky session expiring and the exit address changing, or the concurrent connection limit filling up in a shared pool. In both cases the application gives no error; the connection simply drops silently. Choose a sticky window longer than your game session and check your limit in the panel.
06Can you play with free proxy lists?
Free lists are suitable for learning the protocol and testing a tool; they are not for a game that holds a continuous session. Who operates these servers is unknown, the drop rate is high, and using them on a connection where you log into an account is an unnecessary risk.
07Does a proxy improve the game's latency?
Generally no. Because an extra hop is added in between, the total path gets longer and latency increases in most setups. The rare exception is when your default route is indirect and the proxy offers a more direct path; that is not a rule and can only be established by measurement.
