Legends of Runeterra Proxy: Connection Model, NAT and the Scope Decision
Most of the advice circulating for Legends of Runeterra is actually borrowed from console shooters: open your NAT type, forward ports, solve the hole-punching problem. This guide first clarifies how the connection is really carried, then covers account security and the scope of router-level configuration.

Legends of Runeterra runs through a Riot client — the launcher on desktop, its own app on mobile. On the network side you see four distinct jobs: account session, match state, content downloads, and the store and collection interface. Even though they come together in a single window, they go to different endpoints and behave differently under your proxy rule.
Let us correct an important misconception up front. In a competitive card game, match state is held on the server, not on players' computers; the client sends decisions and receives the updated state. This model does not require a direct connection between players. Consequently, the NAT type and port forwarding advice familiar from console games has limited relevance here.
That leaves two things that really matter: keeping the connection uninterrupted, and behaving consistently with your account's security flows. This page covers both separately.
Where is match state held, and how does the connection branch?
Match state held server-side is a comfortable model from a network design standpoint. Your client connects in one direction only: outbound. It does not need to accept incoming connections, it listens on no port, and it never sees your opponent's address. A side benefit is that your address is never exposed to the other party; in card games this is a clear difference compared with genres that establish direct connections.
The paths the client opens fall into four groups. Identity and session traffic goes over TLS and is short-lived. The match session is long-lived and sensitive to interruption. Content downloads — patches and asset packages — are pulled from a distribution network and account for the largest volume of all items. The store and collection interface consists of many small HTTPS requests.
Knowing this branching simplifies the setup decision. If all you expect from the proxy is coverage of the web surfaces, a narrow rule is enough. If you want to route all of the client's traffic, you need to widen the scope; in that case content downloads pass through the same channel and the cost item grows. The diagram below shows the four paths and the character of each.

The four paths go to different endpoints; the scope of your proxy rule determines which of them is routed.
NAT type, hole punching and the layer a proxy adds
NAT is the mechanism that translates the private addresses behind your router into a single public address. It creates a mapping for every connection you open outbound and uses that mapping to deliver returning responses to the right device. If there is no mapping for a connection arriving unsolicited from outside, the packet is dropped. The technique called "hole punching" exploits the creation of these mappings when both sides initiate outbound connections at the same time, and it is designed for games that try to establish direct connections.
In a model where the client only connects outbound, this mechanism is not needed. The NAT-related problem you will encounter in practice is of a different kind: mapping timeout. Routers drop idle mappings after a while. In a card game with long thinking times, a connection can stay silent for minutes, and when the mapping is dropped the session breaks. The symptom is typical: a sudden connection error after a long turn. For the conceptual difference between NAT and a proxy, see difference between a proxy and NAT article is a good starting point.
A proxy adds one more layer to this picture. There are now two mapping chains: one between your device and the proxy, and one between the proxy and the target. The probability of a drop increases mathematically compared with a single-layer setup, and it becomes harder to tell which link caused the problem. So position the proxy not as a stability solution, but as a tool answering a specific need. If you are curious about its behaviour in the same provider's other games, using a proxy in Valorant and LoL offers a comparison.
Account security, two-step verification and sudden location change
Account security flows are surfaces that also evaluate where the connection comes from. When an account that has logged in from the same country for a long time suddenly connects from another continent, additional verification is expected behaviour, and it is a mechanism that protects your account. If you use a proxy, you produce that trigger yourself.
The practical conclusion is clear: choose your exit country consistently with the account's usual country of use. For an account managed from Turkey, a Turkey exit produces the least friction in terms of both routing and verification flows. If you must change country, do it gradually and rarely rather than suddenly and frequently. If the verification code goes to your e-mail address, bear in mind that trying to access that e-mail account from another country at the same time can start a second verification chain.
Turning off two-step verification may be the first convenience that comes to mind, but it is the wrong direction. Verification is even more valuable if your exit address sits in a shared pool; the behaviour of others using the same address is outside your control. The right approach is to keep verification on and keep the exit fixed. For the trust dimension of provider choice, see is using a proxy safe and for logging practices, proxy logs and privacy the articles open up the topic.
Caution
Never send your credentials through an exit whose origin you do not know. Who operates the servers on free lists is unknown; ignoring a certificate warning and continuing can mean handing your session information, in readable form, to a party sitting in the middle.
Router-level configuration and the difference in scope
The difference between a device setting and network-level configuration comes down to a single question: whom does the rule bind? A proxy defined on a device affects only that device — often only certain applications on that device. A rule defined on the router covers everything that connects to that network: phones, consoles, televisions, smart home devices.
This breadth cuts both ways. The advantage is that it can also cover devices that do not accept a proxy setting. The disadvantage is that it makes diagnosis harder and produces unexpected side effects; the update service of some device on the network is routed to the same exit and quickly consumes a metered quota. Moreover, most home routers are not proxy clients; what they offer is usually routing- or DNS-level configuration, and that is not the same thing as a proxy operating at the application layer. The options using a proxy via the router article.
Follow this order when deciding: first try routing a single application, then move to device-wide if that is not enough, and only move to the network level if it is truly necessary. At each step the scope widens, and when a problem appears it becomes harder to trace back which change caused what. The density table below shows to what extent three configuration points cover six traffic types.

An exit plan for your Runeterra setup
What card games call for is stability; an exit with a fixed address and a rule with correctly chosen scope is enough.
Choose whichever you need from our residential proxies, datacenter proxies, IPv6 and ISP solutions. Every plan comes with unlimited options, 99.9% uptime, rotating proxies, sticky sessions and 24/7 support. Ideal for web scraping, ad verification, SEO monitoring and digital data collection.
ISP ProxyStatic Turkish IPs registered to an ISP
ISP-registered static Türkiye IPs; they combine datacenter speed with the reputation of a real carrier. Ideal for long sessions and low-ping use.
Doing the whole setup in one go and testing the result all at once is a common mistake; when something does not work, you cannot tell which change is responsible. Reverse the order: change one variable at each step and verify immediately. First measure independently that the exit is live, then check the address shown in the browser, and open the client last.
It is worth looking at three things separately during verification. The first is the exit address and its country. The second is where domain resolution happens; if resolution stays on your local server, the target names are visible to your provider. DNS leak test measures this. The third is IPv6 behaviour: if your exit is IPv4 only and IPv6 is enabled on your device, a request to a target reachable over IPv6 can bypass the proxy entirely. The symptom is insidious because the page opens, no error appears, and the setup looks like it is working.
Finally, keep records. Write down which device, which scope, which protocol and which exit you are working with. When a problem appears a few days later, that three-line note eliminates hours of trial and error. For behavioural details on the SOCKS5 side, what a SOCKS5 proxy is is the core reference.
Change one variable at each step and test immediately.
Choose an exit country consistent with the account's usual country.
Do not run a second tunnel layer at the same time.
Keep the scope at the narrowest level that does the job.
Keep the configuration and exit label written down.
Symptoms, likely causes and the order of checks
When troubleshooting, reading the symptom correctly is half the solution. The table below summarises the situations most often encountered in the field and where to look first; following the order faithfully prevents unnecessary configuration changes.
Symptom
Possible cause
Where to look first
Connection drops after a long turn
The NAT mapping timed out
Router session duration and the stability of the exit
Extra verification requested at login
Exit country differs from usual usage
Match the exit country to the account's country
The client opens but the collection comes up empty
Small requests are timing out
Concurrent connection limit and exit load
Patch download is very slow
Distribution node in a distant region
Move downloads outside the proxy scope
Other devices on the network have slowed down too
Broad scope at router level
Reduce the scope to device level
A certificate warning appears
The TLS session is being opened at an intermediate point
Do not dismiss the warning; change the exit
Remember one rule when using the table: never make two changes at once. If you change both the exit and the scope while investigating a disconnection problem, you will not know which one helped even if the problem goes away, and you will start over when the same fault recurs.
Where does the data volume go?
If you use an exit billed on metered data, knowing where the quota goes is directly a budget matter. In card games the match traffic itself is small; the real volume comes from patch and asset downloads. When a new set is released, the downloaded package can carry more data than the total of months of matches.
The second largest item is the interface. The collection screen, deck builder and store front pull card images, and although these images are cached, the first load accounts for a considerable volume. The third item is the launcher's background requests: version checks, the announcement feed and status information repeat at regular intervals even when you are not playing.
The reduction method is simple and consists of two steps. The first is to keep large downloads outside the metered exit; temporarily narrowing the scope on patch days is the single most effective move. The second is to actually close the launcher when you are not playing; a client running in the background quietly consumes data under a broad rule. The distribution below shows the relative weight of the items.

The shares are not real measurements but representative values describing relative weight over a typical period of use.
Latency expectations and cases where a proxy is not needed
A proxy inserts a hop and increases total latency in most setups; a proxy does not reduce latency and is not a ping improvement tool. In a turn-based card game, the effect of this increase on gameplay is generally small, but it would not be right to claim it is zero either: animation transitions and turn hand-offs take a little longer. In the rare cases where your default route is unusually circuitous the picture can reverse, but that is not a rule — it is an exception to be confirmed only by measurement.
The scenarios in which a proxy is genuinely meaningful in this game are narrow. Using a fixed exit point from a corporate network, diagnosing at which point a network policy cuts off traffic, verifying how the store front looks in a different region, and defining a consistent exit in a multi-device environment are the main ones. Beyond these, if you play from your own home in your own country, the added layer brings only latency, cost and diagnostic difficulty.
If you want to clarify the distinction between scope and purpose, it helps not to confuse two tools: a proxy is a routing rule covering wherever it is defined, whereas a tunnel wrapping all of a device's traffic establishes a separate transport layer. For the details of the difference, see the difference between a proxy and a VPN You can look at the article. And to see the equivalents in other titles, game proxy guides the section is a suitable starting point.

Legends of Runeterra proxy questions
01Do I need to open my NAT type or forward ports?
In a game whose match state is held server-side, the client only connects outbound; since it never waits for an incoming connection, it has no need for port forwarding. The NAT advice familiar from console shooters does not apply directly to this model.
02My connection drops after a long turn — why?
The most likely cause is an idle NAT mapping timing out on the router. In turns with long thinking times, the connection can stay silent for minutes. Adding a proxy increases this risk, because two separate mapping chains are then involved.
03Is it better to configure the proxy on the router?
Only if you need to cover devices that do not accept a proxy setting. Network-level configuration affects every device; diagnosis becomes harder and a metered quota is consumed quickly. Staying at the narrowest scope that does the job is the healthier choice.
04What happens to my account if I change the exit country?
A login from an unusual location may prompt additional verification; that is expected behaviour protecting your account. Choosing an exit country consistent with the account's usual country of use produces the least friction.
05Should I turn off two-step verification?
No. Verification is even more valuable if you use a shared exit, because the behaviour of other people using the same address is outside your control. The right approach is to keep verification on and keep the exit fixed.
06My quota runs out quickly — which item is responsible?
Almost always patch and asset downloads. On new set releases, the downloaded package alone accounts for a large share. Temporarily narrowing the scope on patch days and closing the launcher when you are not playing are the two most effective moves.
07Does a proxy speed up the gaming experience?
No. Because of the added hop, total latency increases in most setups. The effect is small in a turn-based game, but building a setup expecting a speed gain would be a mistake; the exception can only be confirmed by measurement.
