Note: How to reverse proxy a Minecraft server with Nginx

Check your kernel version >= 4.9

uname -a

Enable BBR

sysctl -w net.core.default_qdisc=fq
sysctl -w net.ipv4.tcp_congestion_control=bbr
sysctl -w net.ipv4.tcp_notsent_lowat=16384
sysctl -p

Add stream config to /etc/nginx/nginx.conf

stream {
include /etc/nginx/tcp.d/*.conf;
}

Create a new config for Minecraft server

upstream [YOUR_MINECRAFT_SERVER] {
server [YOUR_MINECRAFT_SERVER]:[PORT];
}
server {
listen [PORT];
proxy_pass [YOUR_MINECRAFT_SERVER];
 
}

Test Nginx config

nginx -t

Reload Nginx

nginx -s reload

Optional: Add DNS SRV record

Name     _minecraft._tcp.[YOUR_MINECRAFT_SERVER].tld
Priority [0-65535]
Weight   [0-65535]
Port     [PORT]
Value    [YOUR_MINECRAFT_SERVER]
