nginx 绑定域名，求帮助

nginx绑定域名；

在内网可以wget mydomain.com
但是在外网却不行 wget mydomain.com

我就是把默认的 site-avaliable/default 中的server_name 改了下。

server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;

root /usr/share/nginx/html;
index index.html index.htm;

# Make site accessible from http://localhost/
server_name mydomain;

location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ =404;
# Uncomment to enable naxsi on this location
# include /etc/nginx/naxsi.rules
}

# Only for nginx-naxsi used with nginx-naxsi-ui : process denied requests
#location /RequestDenied {
# proxy_pass http://127.0.0.1:8080;

用的西部数码的主机，不是到是不是他们的问题。（提个工单都要钱，无语）
