在把我的家用服务器升级到 Ubuntu 24.04 之后遇到了一个奇怪的问题。Docker 容器启动正常，但从局域网外访问 8080 端口的请求都会超时。UFW 已关闭，而且该端口正在监听。网络默认设置是不是有什么变化？

Running into a weird issue after upgrading my home server to Ubuntu 24.04. Docker containers start fine, but anything hitting port 8080 times out from outside the LAN. UFW is off and the port is listening. Did something change with networking defaults?
