A simple and fast software designed to bypass Deep Packet Inspection.
See the installation guide for SpoofDPI here.

-addr string
listen address (default "127.0.0.1")
-banner
enable banner (default true)
-debug
enable debug output
-dns-addr string
dns address (default "8.8.8.8")
-dns-port int
port number for dns (default 53)
-enable-doh
enable 'dns-over-https'
-pattern value
bypass DPI only on packets matching this regex pattern; can be given multiple times
-port int
port (default 8080)
-system-proxy
enable system-wide proxy (default true)
-timeout int
timeout in milliseconds; no timeout when not given
-v print spoofdpi's version; this may contain some other relevant information
-window-size int
chunk size, in number of bytes, for fragmented client hello,
try lower values if the default value doesn't bypass the DPI;
when not given, the client hello packet will be sent in two parts:
fragmentation for the first data packet and the rest
If you are using any vpn extensions such as Hotspot Shield in Chrome browser, go to Settings > Extensions, and disable them.
Run spoofdpi
and it will automatically set your proxy
Run spoofdpi
and open your favorite browser with proxy option
google-chrome --proxy-server="http://127.0.0.1:8080"
Since most websites in the world now support HTTPS, SpoofDPI doesn't bypass Deep Packet Inspections for HTTP requests, However, it still serves proxy connection for all HTTP requests.
Although TLS encrypts every handshake process, the domain names are still shown as plaintext in the Client hello packet. In other words, when someone else looks on the packet, they can easily guess where the packet is headed to. The domain name can offer significant information while DPI is being processed, and we can actually see that the connection is blocked right after sending Client hello packet. I had tried some ways to bypass this and found out that it seemed like only the first chunk gets inspected when we send the Client hello packet split into chunks. What SpoofDPI does to bypass this is to send the first 1 byte of a request to the server, and then send the rest.
