TUN Mode (Virtual Network Adapter): Full-System Traffic Forwarding

• TUN mode creates a virtual network adapter on your device, intercepting and forwarding all traffic at the network (IP) layer. This ensures that all apps and services — even those that don’t support proxy settings — are routed through the VPN.

• Advantage → Full system coverage for all traffic.
• Limitation → Because it works at the routing level, connections may be less stable under certain devices or network environments.

System Proxy: Consistent Stability

• By attaching your system’s HTTP proxy directly to the VPN service, System Proxy offers a more stable and consistent connection.
• Advantage → Smooth, reliable, and stable performance.
• Limitation → Because some apps and websites do not support proxy mode, they may still be blocked in certain situations.

If you’re being repeatedly asked to sign in when selecting a connection, don’t worry — this can be easily fixed.

Solution:
Simply log in again using your username and password. Once you’ve successfully signed in, the extension will automatically remember your credentials for that specific connection the next time you use it.

No further action is needed.

If you're seeing a “VCRUNTIME140_1.dll not found” error when launching 5UF VPN, don’t worry — this is a common issue and can be resolved quickly.

This error occurs when your system is missing a required component from the Microsoft Visual C++ Redistributable package, which is used by many Windows applications.

Follow the guide below to fix it safely and get 5UF VPN running again.

Global:

This means all your internet traffic goes through our proxy servers to keep you safe and private.

But, you can choose certain IP addresses or areas (regions) where traffic will go directly without using the proxy.

Why Use This?

• Keep most of your browsing private and secure.

• Let trusted places (like your home or work network) connect directly for better speed and reliability.

• You decide which traffic uses the proxy and which doesn’t.

---

Partial: 

This means most of your internet traffic goes straight to websites without using a proxy. This keeps things fast.

Only the websites or places you pick (by IP or region) will go through the proxy to stay private or access special content.

Why Use This?

• Fast internet for most sites.

• Extra protection only where you want it.

• You choose which traffic uses the proxy.

“Unlimited data” means we do not ban or charge extra for high usage, but we enforce a Fair Usage Policy (daily cap) to ensure fair performance for everyone. Why?

• Without limits, a few users may abuse the service (e.g. servers, heavy sharing), slowing others down.
• VPN servers cost bandwidth, which must be shared efficiently.
• Most “truly unlimited” VPNs silently limit users. We state it clearly.

Example: Our unlimited plan may cap at 20–30GB/day. Beyond that, your speed may drop or pause until the next day. If you accidentally exceed the limit, you can contact our support to restore access. As long as it is not shared by multiple users or maliciously resold, we can restore it immediately.

If you are only visiting China for a short time and do not rely heavily on international services, roaming with your international SIM card is possible. Most major providers (AT&T, Vodafone, T-Mobile, etc.) offer roaming in China, and these connections often bypass the Great Firewall (GFW), allowing direct access to global services. However, note:

• Roaming is very expensive — often $10–15/day
• Speed is usually limited and may have daily caps
• Not suitable for long-term or high-volume use

If you plan to stay in China longer, or rely on access to services like Gmail, YouTube, Instagram, Google Docs, WhatsApp, we strongly recommend:

• Buying a local SIM card (e.g. China Unicom, China Telecom)
• Using a secure VPN to bypass the GFW

Popular services blocked in China without VPN include:

• Search: Google, Bing (EN), DuckDuckGo
• Social: Facebook, Instagram, Twitter, Threads, Snapchat, X
• Messaging: WhatsApp, Telegram, Signal, Messenger, Line
• Streaming: YouTube, Twitch, Spotify, Netflix (partially)
• Cloud: Google Drive, Dropbox, OneDrive, iCloud (partly)
• Email: Gmail, ProtonMail, Outlook (unstable)
• News: BBC, CNN, NYT, Wikipedia (EN)

Yes. You can now customize the spoofed domain. Choose a trusted and globally accessible domain to maximize connection success.

SNI spoofing replaces the actual domain with a “safe-looking” one (like bing.com) during TLS handshake to bypass domain-based restrictions. Useful when VPN access is blocked.

Does SNI spoofing work in all network environments?  

Not always. Some advanced networks inspect TLS fingerprints or certificate data. SNI spoofing improves success rates but is not guaranteed.

Can SNI spoofing help save mobile data?  

Some mobile carriers offer zero-rated data for specific domains (e.g., music or video apps). SNI spoofing may help you benefit from these packages.

Can I choose a custom spoofed domain?  

YES.

Will SNI spoofing affect the VPN server I’m connecting to?  

No. This only affects the domain name in the handshake phase. Your real traffic still goes to the selected VPN server.

The first time you use the app, a pop-up will appear asking for permission to create a VPN. If you deny it at this time, it will always be denied in the future, so you will need to reinstall it.

All traffic is routed through the 5UF App, so its usage appears high in battery stats. Actual battery impact is minimal.

Q:和智能WEB代理的关系

此产品和智能web代理是互为替代或者是配合的产品,所添加的规则自动同步在同一个帐号下.

这些规则可以通过我们的网站控制台管理,也可以通过插件来管理,是同步的.

在一些不支持这个插件的环境下,可以继续使用智能web代理,如在iPhone里.

Q:如果在电脑里同时设置了智能web代理和超级VPN,那个生效?

超级VPN只在chrome里有效,如果你安装了这个插件,那么在Chrome里以这个插件为准,系统的智能代理就会失效,但不影响IE,Safari等使用系统代理的软件.

你安装了超级VPN,即使"关闭"状态下,系统的代理也是不生效的.

Q:多台电脑同时使用的情况下规则如何同步?

以最后提交一次为准其它电脑会自动同步.

Q:如果我把域名同时加入到白名单(不加速列表)和"加速规则"里,那个优先?

以白名单为优先,比如你把baidu.com同时加入了,但访问的时候是不加速的.

Q:什么情况下需要使用白名单?

我们系统插件默认包含了GFWlist里项目里所有域名,且定时更新.如果你GFWlist里的域名你不需要加速,请加入到白名单里.

其它情况下无需操作.

GFWlist里的白名单我们没有完全采用,因为我们的发现fonts.googleapis.com这个域名被加入到白名单,但实际上中国大陆很多地方已经不能访问这个域名,所以会非常影响网页打开速度.

If you only renewed and didn’t upgrade, your flow from the current period is not reset. Upgrade to a higher VIP level to reset flow immediately and recalculate the cycle.

VPN encrypts your data but still uses your mobile or Wi-Fi connection. It does not save mobile data. If you're on Wi-Fi, mobile data is not used. You must have internet access to use VPN.

VIP is time-based with different monthly packages. Free users get 50MB/hour. VIP 1–4 packages differ in price, flow cap, and concurrent device limits. Unlimited plans still have daily usage caps to prevent abuse.

If you only renewed (not upgraded), your data won’t reset — it only extends your membership period. To reset data immediately, you need to upgrade your plan. It will take effect right away and start a new billing cycle. “Unlimited data” means no cap under normal use — browsing, streaming, downloads are all fine. However, the following will trigger limits:

• Reselling or sharing your account
• Heavy P2P usage or massive video downloads
• Using over 10GB/day (VIP3 limit)

If flagged as abuse, you may be throttled temporarily. Data will reset the next day.

When you upgrade, we calculate your remaining days × price and convert them into time under the new plan. No loss. For example, if you have VIP2 and upgrade to VIP4, your unused time will be converted into VIP4 days, then added to the new time. Note: Upgrading starts a new billing cycle immediately and resets your data. "Renewing" simply extends your current plan — it does not upgrade or reset anything.

iOS App Store payments recharge your account balance. VIP uses monthly billing cycles, and upgrades convert unused days into the new plan rate. Upgrading resets flow and cycle start date.

First check if you could connect before. Try switching servers or networks. Run: ping hk2.xinhuanet.network. If timeout, contact support. Try: telnet hk2.xinhuanet.network 1723. If blocked, port 1723 may be filtered. Try L2TP, SSTP, etc.
