VLESS Reality for Iran in 2026: setup, SNI checks, and troubleshooting
This page is the hub for Iran-related VLESS Reality searches: client setup, SNI selection, OpenWRT routing, mobile testing, and failure diagnosis. It does not list public free configs. The focus is durable checks for people who already have a legitimate endpoint, or who need a paid managed VLESS proxy.
Treat VLESS Reality for Iran-related traffic as a setup workflow: pick a maintained client, import a private endpoint, verify Reality and SNI fields, test DNS and exit IP, then debug TLS, clock, routing, and mobile-network failures. Skip public free configs. They churn fast and are a security risk.
VLESS Reality guidance for 2026 has to stay careful and current without pretending one universal config exists. The moving parts, local network tests, and fallback options matter more than a copied profile that worked for someone else.

What this page is for
Iran-related search demand sits on VLESS, Xray, Reality, SNI, OpenWRT, v2rayNG, and error strings more than on generic Poland proxy keywords. So this page covers protocol setup first, then points people at a managed mobile proxy only when the technical need is clear.
This is not a free-config directory. Public VLESS links are unstable, often abused, and hard to quality-control. Better to teach how to validate a private endpoint, show where failures actually sit, and sell a paid dedicated endpoint when reliability matters.
Safe setup path for VLESS Reality
Use a maintained client: 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 provider you trust or from infrastructure you control. Then confirm UUID, port, flow, security, public key, short ID, and serverName match the endpoint.
Test in this order: client starts without core errors, Reality handshake succeeds, DNS follows the intended path, exit IP matches the expected network, and target sites load without repeated TLS or timeout failures. That order stops you from guessing SNI when the real problem is clock drift, DNS leakage, or a bad share link.
Validation order
Client starts, Reality handshake succeeds, DNS stays on the intended path, exit IP checks out, then you test target reachability.
How to treat SNI and Reality fields
SNI is not a magic keyword. With Reality, what matters is whether the endpoint's serverName, public key, short ID, flow, and destination behavior match what the client sends. Blind SNI swaps can turn a working endpoint into a verification failure.
When something breaks, write down the client name, 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 quick. Windows users often pick v2rayN because logs, tray routing, and core selection are easier to inspect. Treat OpenWRT as a second-stage setup after the endpoint already works on one device.
OpenWRT adds failure points: CPU limits, nftables or iptables rules, DNS forwarding, transparent proxy rules, and per-device routing. Prove the same VLESS link on a phone first. Move it to the router only after the endpoint is 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. OpenWRT only pays for its complexity when every LAN device needs routing at once. Do not start a router rebuild on an unstable link; that burns the short window you 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 happens after throttling. Treat them as separate tests: one result on mobile data, one on Wi-Fi. If mobile data connects and Wi-Fi does not, credentials are fine and the home line is the problem. If both fail the same way, check endpoint fields, client core, or clock before you touch SNI.
During a heavy blackout or sudden slowdown, try the cheap checks first. Switch Wi-Fi to mobile data (or back), set the device clock to automatic, and re-import the share link instead of editing fields by hand. Do not swap serverName values or rebuild OpenWRT routing mid-outage. If nothing connects on either network for a long stretch, the issue is usually upstream reachability, not your config. Wait and retry rather than churn settings.
Pick the deeper read by symptom. If a working setup broke after someone changed a hostname, open the SNI guide and verify fields before changing anything. If you see verification failures, TLS timeouts, or a connection that is up while the IP never changes, open the troubleshooting guide and map the error to its layer. If one device is solid and you want the whole household routed, open 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 client fields do not match server fields, the clock is wrong, or the endpoint destination changed. TLS handshake timeout more often points 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 and Wi-Fi fails, compare DNS, IPv6, and ISP filtering. If Wi-Fi works and mobile data fails, try another transport or a managed endpoint with better mobile-network reachability.
When a paid managed endpoint makes sense
A paid VLESS/Xray mobile proxy fits when you need stable credentials, support you can reach, and a real carrier exit IP instead of hopping through unknown public links. It works best for testing, automation, and anything that needs one consistent endpoint with clear ownership.
Proxy Poland sells this as managed VLESS/Xray on real mobile infrastructure, not as a censorship-bypass promise. What you get: reliability, private credentials, mobile IP verification, and 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.
