VPN for ChatGPT, Claude, and Gemini
Where AI services are restricted, why, and how to get reliable access from those regions.
Where AI services are restricted
The big AI providers all geo-restrict access, with overlapping but not identical restricted-country lists. Two layers of blocking exist: the provider's own terms (OFAC sanctions, country-specific regulatory exclusions) and upstream network filtering by the user's own ISP or government.
- ChatGPT (OpenAI): unsupported countries include Russia, China, Iran, Cuba, Syria, and North Korea. Italy briefly banned ChatGPT in March-April 2023; lifted after OpenAI added consent flows.
- Claude (Anthropic): similar restricted list, primarily driven by OFAC. Available in more countries than ChatGPT but still excludes the main sanctioned jurisdictions.
- Gemini (Google): tied to Google account country and broader Google service restrictions. Available in most countries where Google operates.
- Perplexity, Character AI: generally available wherever the platform's hosting CDNs are reachable, but specific features may be geo-restricted.
- Network-level blocks: Russia, China, and Iran block OpenAI's IP ranges at the upstream level, even when the user has a valid account. UAE and Saudi Arabia have been more permissive on AI access.
Two problems, two solutions
The upstream-block problem (your ISP cannot reach OpenAI) is what a VPN solves directly. Connect to a VPN exit in a country where ChatGPT is unrestricted, route your traffic through it, and the upstream block does not apply. This is the part that requires a VPN protocol that survives your local DPI environment.
The account-level problem (OpenAI does not let users from your country create accounts) requires a non-restricted phone number and payment method at sign-up. A VPN does not solve this directly: it changes your IP, not your phone number. Many users in restricted countries either use accounts created before they travelled, or use virtual phone numbers from non-sanctioned countries.
Why standard VPNs fail in DPI-heavy markets
In Russia, China, Iran, Pakistan, and Turkey, a VPN connection has to survive deep packet inspection before it can do anything else. WireGuard's 148-byte handshake gets fingerprinted within milliseconds. OpenVPN's TLS handshake is detected too. Most "obfuscated" or "stealth" modes from major VPN brands wrap one of these in TLS padding, which DPI hardware has been pattern-matching since 2023.
Fexyn Stealth uses VLESS Reality with the Vision flow. The handshake is a real TLS 1.3 handshake to a real public site like microsoft.com. The certificate the carrier sees is the actual Microsoft certificate. There is no fake handshake to fingerprint, and the Vision flow eliminates the nested-TLS pattern that would otherwise be detectable through traffic analysis.
Setup: ChatGPT + Fexyn in five minutes
- Install before you arrive in country. Russian, Chinese, and Iranian ISPs block most VPN provider websites at the DNS layer. Sign up at fexyn.com/register and download from fexyn.com/download/windows from outside the country.
- Get an account from a non-restricted country. Either an OpenAI / Anthropic / Google account you created before travelling, or one created with a non-sanctioned phone number and payment method. The VPN does not solve the account-level geo-check.
- Pin the right protocol. For Russia, China, Iran: pin Fexyn Stealth as default. For UAE, Saudi Arabia, Pakistan: also Stealth. For everywhere else: Bolt (WireGuard) is faster.
- Connect to a server in a country where ChatGPT is unrestricted. Frankfurt is the standard choice; Cyprus is closer from the Gulf and Iran; Helsinki from Russia.
- Open ChatGPT, Claude, or Gemini. They should work normally. If you see a country-restriction message, your account country is the issue (not the VPN); see step 2.
The legal question
Using a VPN to access AI services is not specifically illegal in any country we are aware of. The provider's terms of service may technically prohibit accessing the service from a sanctioned country (OpenAI's terms do); enforcement against individual users is rare and almost always limited to account suspension rather than legal action. This is not legal advice. For users in jurisdictions where general VPN use carries legal exposure (UAE Article 9, Saudi Article 6, Iran's Computer Crimes Law), the legal framework around AI access is the same as the legal framework around any other VPN-mediated activity. The country-specific picture lives on each country page.
Frequently asked
Why is ChatGPT not available in my country?
OpenAI restricts ChatGPT availability by IP and account country. The unsupported list includes Russia, China, Iran, Cuba, Syria, North Korea, and several others. Some restrictions are OFAC-driven; others reflect country-specific regulatory concerns. Italy briefly banned ChatGPT in March-April 2023 over GDPR concerns; the ban was lifted after OpenAI added consent flows. Other geo-restrictions exist for specific features (image generation in some regions, voice mode in others) without affecting the core text interface.
Does ChatGPT block VPN traffic?
OpenAI does not aggressively VPN-detect. The primary geo-check is at sign-up (which country your phone number and payment method come from) rather than at every API call. Once an account is created, ChatGPT works from most VPN exit IPs. The harder problem is being in a country where the upstream network blocks OpenAI's IP ranges (Russia and China both do this). Standard WireGuard sometimes works there; VLESS Reality consistently does. Claude and Gemini behave similarly: light account-level geo-checks, harder upstream blocking from a few countries.
Can I use ChatGPT in China with a VPN?
Yes, with the right protocol. ChatGPT is blocked at the network level in China (the Great Firewall blocks OpenAI's IP ranges) and at the account level (OpenAI's terms exclude China). Standard WireGuard or OpenVPN does not survive the GFW, so the VPN itself fails before you can reach ChatGPT. VLESS Reality with the Vision flow handshakes through the GFW reliably; once tunneled, ChatGPT works as expected. You will also need a non-Chinese phone number for sign-up if you do not already have an account.
Can I use ChatGPT in Russia with a VPN?
Yes. Russia's TSPU blocks OpenAI's IPs and most standard VPN protocols (WireGuard, OpenVPN, plain VLESS). VLESS Reality with the Vision flow continues to work. Once your VPN is connected to a Frankfurt or Helsinki exit, ChatGPT works normally. Use a non-Russian SIM or virtual phone number if you do not have an existing OpenAI account; OFAC restrictions make new account creation from a Russian phone number difficult. Read [our deep dive on Russian network conditions](/blog/russia-vpn-what-works-2026).
Can I use ChatGPT in Iran with a VPN?
Yes, but it is the hardest case in our list. Iran's filtering is intense: OpenAI's IPs blocked at the network level, OFAC sanctions blocking OpenAI account creation from Iranian phone numbers, and the broader filtering infrastructure that requires Reality+Vision to handshake at all. Get an account first (use a non-Iranian phone number, or have an account from before you traveled). Use Fexyn Stealth pinned as the default protocol. Frankfurt or Cyprus exit. Iranian users are an active part of the AI community despite all of this; the inconvenience is real but the pattern is well-trodden.
Which Fexyn protocol works for ChatGPT?
On networks without active VPN filtering (most of Europe, North America, parts of Latin America), Fexyn Bolt (WireGuard) is the right choice. Lower latency, faster connection. On networks that filter VPN protocols (Russia, China, Iran, UAE, Pakistan), pin Fexyn Stealth in app settings. Stealth is the only protocol that handshakes reliably through TSPU, the GFW, and the Iranian filtering infrastructure. [The protocol guide explains why](/blog/vless-reality-protocol-guide).
