webRTC'；s使用专用和公用IP地址（如Stackpath或AWS EC2）进行设置？

我花了很多时间试图使Coturn在同时具有Public（Public_ID_ADDRESS）和Private（Private_ID_ADDRESS）IP地址的vm上工作。下面的工作，可能有人会发现它的帮助。 当然，用IP地址替换公共ID地址和私有ID地址

1） 我通过在/www/js/main.js中添加

iceTransportPolicy:“relay”

来阻止点对点测试回合服务器，请参见下文 2） 我使用443而不是默认的3478端口，用于使用自定义TURN coturn服务器的TURN通信 3） $sudo ufw status下方仅显示打开的端口

   22/tcp                     ALLOW       Anywhere
   80/tcp                     ALLOW       Anywhere
   443/tcp                    ALLOW       Anywhere
   443/udp                    ALLOW       Anywhere
   22/tcp (v6)                ALLOW       Anywhere (v6)
   80/tcp (v6)                ALLOW       Anywhere (v6)
   443/tcp (v6)               ALLOW       Anywhere (v6)
   443/udp (v6)               ALLOW       Anywhere (v6)

文件：

/etc/hosts

   127.0.0.1       localhost
   127.0.1.1    mycoturn.com
   PRIVATE_ID_ADDRESS mycoturn.com

    # The following lines are desirable for IPv6 capable hosts
    ::1     localhost ip6-localhost ip6-loopback
    ff02::1 ip6-allnodes
    ff02::2 ip6-allrouters

确保TURN服务器具有正确的主机名：

$sudo hostnamectl set hostname mycoturn.com

文件：/etc/turnserver.conf

listening-port=443
tls-listening-port=443
listening-ip=PRIVATE_ID_ADDRESS
relay-ip=PRIVATE_ID_ADDRESS
