Перевірено на прошивці OpenWrt 22.03.5 r20134-5f15225c1e

1. Оновлюємо package manager: opkg update
2. Встановлюємо потрібні пакети: opkg install iptables iptables-mod-nat-extra redsocks
3. Запускаємо команду: service redsocks stop && mv /etc/redsocks.conf /etc/redsocks.conf.bkp && cd /etc && wget https://github.com/emonbhuiyan/Redsocks-OpenWRT/raw/main/redsocks.conf && mv /etc/init.d/redsocks /etc/init.d/redsocks.bkp && cd /etc/init.d && wget https://github.com/emonbhuiyan/Redsocks-OpenWRT/raw/main/redsocks && chmod +x /etc/init.d/redsocks

Після встановлення вбиваємо налаштування проксі у цей файл /etc/resocks.conf

base {
        log_debug = off;
        log_info = on;
        log = "syslog:local7";
        daemon = on;
        redirector = iptables;
}

redsocks {
        local_ip = 0.0.0.0;
        local_port = 1337;
        ip = xx.xx.xx.xx;
        port = xxxx;
        type = socks5;
        login = "username";
        password = "password";
}
