Usage: goodbyedpi.exe [OPTION...]
-p block passive DPI
-q block QUIC/HTTP3
-r replace Host with hoSt
-s remove space between host header and its value
-m mix Host header case (test.com -> tEsT.cOm)

Modern modesets (more stable, more compatible, faster):
-5 -f 2 -e 2 --auto-ttl --reverse-frag --max-payload (this is the default)
-5 -f 2 -e 2 --auto-ttl --reverse-frag --max-payload

-9 -f 2 -e 2 --wrong-seq --wrong-chksum --reverse-frag --max-payload -q (this is the default)
Note: combination of --wrong-seq and --wrong-chksum generates two different fake packets.
```
To check if your ISP's DPI could be circumvented, first make sure that your provider does not poison DNS answers by enabling "Secure DNS (DNS over HTTPS)" option in your browser.
