caddy-randomipv6
Trying to create an IPv6_Randomizer to hide the users ip at reverse proxies. Made for my mastodon instance, previously using LUA with openresty.
After quite some config attempts, this is how it works in a Caddyfile.
I don't know why, but X-Forwarded-For kept getting overwritten until I did a header_up with ... the X-Forwarded-For Header? Which then used the modules generated random ipv6.
For randomizing within php environment:
domain.tld {
root /var/www/html/public
file_server
randomipv6
php_fastcgi unix//run/php/php8.4-fpm.sock {
header_up X-Forwarded-For {header.X-Forwarded-For}
}
}
For randomizing for a reverse proxy:
domain.tld {
randomipv6
reverse_proxy http://127.0.0.1:8080 {
header_up X-Forwarded-For {header.X-Forwarded-For}
}
}
