[Web] Apache2在内网中可以访问，通过外网就不能访问，请帮忙看一下，谢谢！

[weixin_38112462]

我在一台FreeBSD6.0的机器上，安装了apache2,我可以通过内网访问这台电脑的网页，但是通过外网就不能打开网页，我这台电脑是通过ADSL上网的，我通来动态域名可以访问这台电脑，就是网页打不开，通过netstat -a 可以看到80端口是打开的，而我在内网也是可以访问网页的。一样的设置，在有固定外网IP的电脑上就可以访问。我想是不是域名的关系，客户端访问的时候，要查询域名，而我的是动态域名，但我用拔号获得的IP也是访问不了。请熟悉的兄弟帮我看一下。谢谢！

我的httpd.conf文档内容如下：
