 防火墙只放行 docker 网段:`ufw allow from 172.16.0.0/12 to 172.17.0.1 port 7891 proto tcp`。compose 默认网络已固定在 `UMT_SUBNET`(缺省 172.30.0.0/24,与本机其他网络冲突时在 `.env.deploy` 改成 172.16.0.0/12 内的空闲网段,如 172.16.80.0/24),否则 compose 自动分配的 192.168.x 网段不在放行范围内。Deno 的 fetch 会读 `HTTP(S)_PROXY`/`NO_PROXY`;TMDB、境外 Pi 上游、camofox 访问境外站都经此代理,站内(postgres/camofox)不走代理。
