делаю запрос: curl -x socks4a://192.168.0.1:1001 ipinfo.io
tcpdump показывает, что от Windows к Linux идет обычный TCP handshake, а не TCP Fast Open:

> SYN
< SYN,ACK
> ACK
> PSH,ACK
< ACK

Windows 11 (192.168.0.1):

fakeresolve
auth iponly
allow * *
parent 1000 socks4+ 192.168.0.2 1001
socks -p1001 -ocUSE_TCP_FASTOPEN, -osUSE_TCP_FASTOPEN, -olUSE_TCP_FASTOPEN, -orUSE_TCP_FASTOPEN, -oRUSE_TCP_FASTOPEN
flush
end

Linux Debian 12 (192.168.0.2):

nserver 8.8.8.8
nscache 65535
auth iponly
allow * *
socks -p1001 -ocUSE_TCP_FASTOPEN, -osUSE_TCP_FASTOPEN, -olUSE_TCP_FASTOPEN, -orUSE_TCP_FASTOPEN, -oRUSE_TCP_FASTOPEN
flush
end

Почему USE_TCP_FASTOPEN а не TCP_FASTOPEN?
