%0A# 说明

当 KVM 存在多个 IP 地址（例如同时连接以太网和 Wi‑Fi，或启用了 VPN）时，H.264 视频模式可能会因为多 IP 环境下的 ICE 错误而无法播放。可以通过限制 WebRTC 使用的网卡来解决此问题。
  1. SSH 登录 KVM，并运行 ifconfig 查看接口名称，例如：
root@blikvm(rw):~# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

  1. 运行 rw 将系统重新挂载为可写，然后编辑 nano /mnt/exec/release/lib/pi/janus_configs/janus.jcfg。找到 ice_ignore_list 配置并设置。例如上面的 KVM 有三个接口，如果你希望 WebRTC 使用 wg0，可以配置为：
ice_ignore_list = "eth0,wlan0"

  1. 重启 web 服务：systemctl restart kvmd-web。

  2. 使用 ro 将系统恢复为只读。

  1. use ro to set system to readonly. :::
