Bypass GFW & DPI Firewalls โ Free VPN Tunneling on Android
Your government blocks the internet. These apps tunnel right through it.
If youโre in Myanmar, China, Russia, Iran, South Korea, or anywhere with heavy internet censorship โ this is how people actually get around it. No root. No paid VPN. Just free Android apps + free SSH credentials.
WTF Is GFW and DPI? (30-Second Version)
GFW (Great Firewall) โ the censorship system that blocks websites, apps, and services in restricted countries. China made it famous. Others copied it.
DPI (Deep Packet Inspection) โ the technology that powers it. Instead of just blocking URLs, DPI looks inside your internet traffic to figure out what youโre doing. Regular VPNs get detected and killed by DPI because it can see youโre using a VPN.
VPN Tunneling โ the workaround. These apps disguise your VPN traffic as normal HTTPS web browsing. DPI sees what looks like regular website traffic. It lets it through. You win.
The 3 Free Android Apps
1๏ธโฃ HTTP Custom โ Easiest to Start With
The most beginner-friendly option. Clean interface. Works with SSH and VPN tunneling out of the box.
What it does: Creates an encrypted SSH tunnel โ wraps it in HTTPS so DPI canโt detect it โ routes all your traffic through it.
How to set it up:
- Install HTTP Custom from Play Store
- You need SSH credentials (username + password + server) โ see โWhere to Get Credentialsโ below
- Open the app โ tap SSH
- Enter your SSH server details:
- Host: the server address you got
- Port:
22(default SSH port) or443if the provider offers it - Username: from your credentials
- Password: from your credentials
- Under Network Settings โ set Proxy Type to HTTPS
- Set Proxy Port to
443 - Tap Connect
- Wait for the green light. Youโre through.
Port 443 is the key. Thatโs the same port regular HTTPS websites use. DPI firewalls almost never block port 443 because blocking it would break every website on the internet.
Available on Play Store โ search โHTTP Customโ
2๏ธโฃ HTTP Injector โ Most Popular, More Features
The power-user favorite. More settings, more payload options, can import config files shared by other users.
How to set it up:
- Install HTTP Injector from Play Store
- Get your SSH credentials (see below)
- Open app โ go to SSH Settings
- Enter:
- SSH Host: your server
- SSH Port:
22(or443) - Username + Password
- Go back โ set Connection Mode to HTTPS/SSL
- Tap the START button
- Connected = youโre past the firewall
Bonus trick: People share working config files (.ehi files) for specific countries. Search your country name + โHTTP Injector configโ โ import the file and connect in one tap. Saves you the manual setup.
Available on Play Store โ search โHTTP Injectorโ
3๏ธโฃ NPV Tunnel โ Lightweight Alternative
Simpler app. Less settings to mess with. Good backup if the other two arenโt working on your network.
How to set it up:
- Install NPV Tunnel from Play Store
- Get SSH credentials (see below)
- Enter server details โ same pattern as above
- Set connection to use port
443 - Connect
Works the same way โ SSH tunnel wrapped in HTTPS. Just a different app doing it.
Available on Play Store โ search โNPV Tunnelโ
Where to Get SSH Credentials (Free)
This is the fuel for all three apps. Without credentials, the apps canโt connect to anything.
Steps:
- Open your browser
- Search: โFree Premium SSH credentialsโ
- Youโll find tons of sites that generate accounts for free
- Pick a server close to your location for better speed (Singapore for SE Asia, Germany for Middle East, US for everywhere else)
- Most sites give you 3-day or 7-day free accounts
- Enter the server, port, username, and password into your tunneling app
- When it expires โ go back โ create a new account โ repeat
Thatโs it. Free credentials โ free tunneling โ free internet. Rinse and repeat forever.
โก Quick Troubleshooting
| Problem | Fix |
|---|---|
| Wonโt connect | Switch port to 443 instead of 22 โ DPI probably blocks port 22 |
| Connects but no internet | Check your proxy settings โ make sure HTTPS proxy is on port 443 |
| Slow speeds | Pick a server closer to your country |
| App crashes | Try a different app from the list โ all three do the same thing |
| Credentials expired | Just generate new ones โ takes 30 seconds |
| Still blocked | Try a different server location โ some IPs get flagged |
Why This Works
- Port 443 = HTTPS = the same thing every website uses. Blocking it would break the entire internet. Firewalls wonโt touch it.
- SSH tunnel = encrypted pipe between you and a server outside your country. Nobody can see whatโs inside.
- HTTPS wrapping = makes that encrypted pipe look like normal web traffic. DPI sees โoh thatโs just someone visiting a websiteโ and lets it pass.
GFW sees HTTPS traffic on port 443. Looks normal. Lets it through. Meanwhile youโre tunneling your entire internet connection through an SSH server in another country. ![]()
Restricted internet is a settings problem. Now you have the settings. ![]()
