VLESS Reality for Iran in 2026: setup, SNI checks, and troubleshooting
Use this guide as the hub for Iran-related VLESS Reality searches: client setup, SNI selection, OpenWRT routing, mobile testing, and failure diagnosis. It avoids public free-config lists and focuses on durable configuration checks for users who already have a legitimate endpoint or need a paid managed VLESS proxy.
VLESS Reality for Iran-related traffic should be handled as a technical setup workflow: choose a maintained client, import a private endpoint, verify Reality and SNI fields, test DNS and exit IP, then troubleshoot TLS, clock, routing, and mobile-network failures. Do not rely on public free configs because they churn quickly and create security risk.
This guide should be careful and current for 2026 without pretending there is a universal configuration. Explain the moving parts in VLESS Reality, how users can test them under local network conditions, and why fallback options matter.

What this page is for
Search Console shows Iran demand around VLESS, Xray, Reality, SNI, OpenWRT, v2rayNG, and error strings rather than generic Poland proxy keywords. That means this page should answer protocol setup intent first, then route qualified users toward a managed mobile proxy only after the technical need is clear.
The page is not a free-config directory. Public VLESS links are unstable, frequently abused, and impossible to quality-control. A better SEO and product path is to teach users how to validate a private endpoint, explain where failures happen, and offer a paid dedicated endpoint when they need reliability.
Safe setup path for VLESS Reality
Start with a maintained client such as v2rayNG on Android, v2rayN on Windows, Streisand on iOS/macOS, or xray-core on a router. Import the private VLESS share link only from a trusted provider or from infrastructure you control, then confirm that UUID, port, flow, security, public key, short ID, and serverName match the endpoint.
After import, test in this order: client starts without core errors, Reality handshake succeeds, DNS resolves through the intended path, the exit IP changes to the expected network, and target sites load without repeated TLS or timeout failures. This order prevents chasing SNI guesses when the real issue is clock drift, DNS leakage, or a malformed share link.
Validation order
Client starts, Reality handshake succeeds, DNS stays on the intended path, exit IP is verified, then target reachability is tested.
How to treat SNI and Reality fields
SNI is not a magic keyword. For Reality, the useful question is whether the endpoint's configured serverName, public key, short ID, flow, and destination behavior match what the client sends. Changing SNI blindly can turn a working endpoint into a verification failure.
When troubleshooting, record the exact client, network type, error message, serverName, security mode, flow, and whether mobile data behaves differently from Wi-Fi. Those details map to fixable causes: wrong Reality key, unsupported flow, blocked destination, stale client core, broken IPv6 route, or DNS interception.
Client routes: Android, Windows, OpenWRT
Android users usually start with v2rayNG because import and mobile-data testing are fast. Windows users often use v2rayN because logs, tray routing, and core selection are easier to inspect. Router users should treat OpenWRT as a second-stage setup after the endpoint works on a single device.
OpenWRT adds more failure points: CPU limits, nftables or iptables rules, DNS forwarding, transparent proxy rules, and per-device routing. Validate the same VLESS link on a phone first. Only move it to the router after the endpoint is proven stable.
Choosing the right path under Iran network conditions
When connectivity is degraded, decide by device first, not by config. If you only need one phone working, stay on v2rayNG: import the private VLESS link, test on mobile data, then on Wi-Fi, and stop there. OpenWRT only earns its complexity when you need every device on the LAN routed at once, and it should never be your first move while the network is unstable, because a router rebuild during a slow or filtered link wastes the window you actually have to confirm the endpoint works.
Mobile data and Wi-Fi rarely behave the same on Iranian networks. A carrier link often reaches a Reality endpoint that a filtered home ISP blocks, and the reverse also happens after throttling. Treat the two as separate tests: keep one result on mobile data and one on Wi-Fi, and let the difference decide your next step. If mobile data connects but Wi-Fi does not, the endpoint and credentials are fine and the home line is the problem; if both fail the same way, suspect the endpoint fields, the client core, or the clock before you touch SNI.
During a heavy blackout or sudden slowdown, try the cheapest checks first. Switch from Wi-Fi to mobile data (or back), confirm the device clock is set automatically, and re-import the share link fresh instead of editing fields by hand. Do not start swapping serverName values or rebuilding OpenWRT routing in the middle of an outage. If nothing connects on either network for an extended period, the issue is usually upstream reachability, not your config, and the right action is to wait and retry rather than churn settings.
Pick the deeper read by symptom, not by curiosity. If a working setup broke after someone changed a hostname, go to the SNI guide and verify fields before changing anything. If you are seeing verification failures, TLS timeouts, or a connection that is up while the IP never changes, go to the troubleshooting guide and map the exact error to its layer. If a single device is solid and you now want the whole household routed, go to the OpenWRT and v2rayNG guide and prove the link on Android before moving it to the router.
Most common failure patterns
Reality verification failed usually means the client fields do not match the server fields, the clock is wrong, or the endpoint destination changed. TLS handshake timeout points more often to routing, port reachability, MTU, IPv6, or network-level blocking than to credentials.
If the client connects but traffic leaks, check DNS first. If only some apps work, check system proxy mode and TUN routing. If mobile data works but Wi-Fi fails, compare DNS, IPv6, and ISP filtering. If Wi-Fi works but mobile data fails, test another transport or a managed endpoint with better mobile-network reachability.
When a paid managed endpoint makes sense
A paid VLESS/Xray mobile proxy makes sense when the user needs stable credentials, predictable support, and a real carrier exit IP instead of rotating through unknown public links. It is strongest for testing, automation, and workflows that need a consistent endpoint with clear ownership.
Proxy Poland should position this as managed VLESS/Xray access on real mobile infrastructure, not as a censorship-bypass promise. The commercial CTA should be reliability, private credentials, mobile IP verification, and support for HTTP, SOCKS5, OpenVPN, and VLESS on one plan.

Frequently Asked Questions
Is this a list of free VLESS Reality configs for Iran?+
No. Free public configs churn within hours, leak credentials, and often inject ads or telemetry. This page explains how to validate a private VLESS Reality endpoint and when a paid managed endpoint is the better choice β it does not host or distribute share links.
What should I check first when VLESS Reality fails?+
Run xray-core in test mode (xray run -test -c config.json), then verify system clock skew (NTP within 30 seconds), UUID, port, flow, security=reality, public key, short ID, serverName, DNS path, and whether the failure differs between Wi-Fi and mobile data β those are the parameters Reality verifies on every handshake.
Should I change SNI until something works?+
No. SNI must match the server's configured serverName and the dest fallback host. Random SNI changes typically break Reality verification and mask the real cause, which is usually a stale public key, an expired short ID, or a destination host that is no longer reachable from the client network.
Can Proxy Poland provide VLESS/Xray access?+
Yes. Proxy Poland plans include VLESS/Xray alongside HTTP, SOCKS5, and OpenVPN on dedicated Polish 4G/5G mobile proxy infrastructure. Each plan includes share-link credentials, a Polish carrier exit IP, and dashboard rotation control.
How does TLS 1.3 fingerprint cloning in Reality actually work?+
Reality copies the ClientHello of a real TLS 1.3 site (the dest target, e.g. www.microsoft.com or apple.com) so middlebox DPI sees a normal HTTPS connection. The xray-core utls library replays Chrome, Firefox, or Safari fingerprints exactly. A wrong fingerprint string (fp=chrome vs fp=firefox) is enough to fail verification on strict probes.
What does the REALITY public-key flow do?+
The server publishes a long-term X25519 public key (pbk). The client's ClientHello carries an authenticated session ticket encrypted to that key. Without the matching pbk and short ID (sid), the server cannot decrypt the ticket and falls back to the dest target β which is what hides the proxy from active probing.
How should I pick the SNI / serverName?+
Pick a publicly reachable TLS 1.3 site that is not blocked in the target network and is not your own infrastructure. Common picks: www.microsoft.com, www.cloudflare.com, www.apple.com. The serverName, dest, and the SNI in the share link must match exactly β Xray will reject a mismatched dest at startup.
What should the dest fallback do?+
Dest is where Xray forwards traffic that fails Reality authentication, so it must be a real, healthy TLS 1.3 service that responds normally to a probe. If a censor's DPI scanner connects, it should see the genuine remote site, not a Xray error. Use port 443 and a host that resolves cleanly via the same DNS the client uses.
Is port 443 or 8443 safer for detection?+
Port 443 blends in with normal HTTPS volume and is the only port that survives strict egress filtering. Port 8443 is recognizable as a non-standard HTTPS port and stands out under flow analysis. Stick to 443 unless your provider forces a different port for routing reasons.
How do GFW DPI and Iran DPI behave differently?+
GFW (China) leans on active probing β it replays your ClientHello to see how the server reacts. Iran DPI relies more on passive flow analysis and SNI denylists. Reality counters active probing well; passive flow signatures are mitigated by Vision flow control (xtls-rprx-vision) and uTLS fingerprint pinning.
Can multiple users share one VLESS endpoint?+
Yes. Xray accepts multiple user UUIDs on a single inbound, each with its own flow setting. The recommended pattern is one UUID per device or per workflow so credential rotation does not affect everyone. Do not share UUIDs across users β there is no per-user logging once a UUID is reused.
What obfuscation alternatives exist if Reality fails?+
If Reality is detected on a network, fall back to Xray with VLESS over WebSocket + TLS behind a CDN, Trojan-go with raw TLS, or Hysteria2 over QUIC for high-loss links. Each has different tradeoffs: CDN-fronted WS is hard to block but slow; Hysteria2 is fast over lossy mobile links but uses UDP which some networks throttle.
