nginx 只能從本機存取

nginx 只能從本機存取

我設定了一個簡單的 nginx 伺服器,只要localhost在瀏覽器中輸入即可運作。如果我嘗試從同一網路中的手機存取它,透過輸入電腦的 IP 位址,我會收到「網頁不可用」訊息。這是我的 nginx.conf:

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/nginx/README.fedora.
include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;
}

http {
    server {
        listen 80;
        location / {
            root /usr/share/nginx/html;
        }
    }
}

根據帖子,我配置了我的防火牆允許家庭區域中的 http,並將無線網路設定在該區域。

iptables INPUT 鏈中的前兩個條目是

Chain INPUT (policy ACCEPT)
target     prot opt source               destination         
ACCEPT     all  --  anywhere             anywhere             ctstate     RELATED,ESTABLISHED
ACCEPT     all  --  anywhere             anywhere            

所以我認為這不是問題。

然而,查看從我的手機捕獲的 tcpdump 請求,我看到了一條回應host unreachable - admin prohibited

21:13:38.514782 IP 192.168.1.3.54982 > sidney.http: Flags [S], seq 2569820651, win 14600, options [mss 1460,sackOK,TS val 3018406 ecr 0,nop,wscale 6], length 0
21:13:38.514934 IP sidney > 192.168.1.3: ICMP host sidney unreachable - admin prohibited, length 68

輸出firewall-cmd --list-all --zone=home

home (active)

可能是什麼問題呢?我使用的是 Fedora 24。
