问题描述
我创建了一个EC2实例，并添加所有的TCP和UDP端口。 ICMP还可以...开始我玩的应用程序与两个端口9000和80，没有制定。该应用程序启动后，我可以从实例连接到它，但我无法从外部连接到它。
I created an EC2 instance and added ALL TCP and UDP ports. ICMP also... Started my play application with both port 9000 and 80, neither worked out. The application starts, I can connect to it from the instance but I cannot connect to it from outside.
远程登录instance_dns_name 9000失败而远程登录instance_dns_name 3389的作品。
telnet instance_dns_name 9000 fails whereas telnet instance_dns_name 3389 works.
我不知道我错过了什么。在微软的Azure同样的问题发生了。但愿这是对区域？
I don't know what I am missing. The same issue happened in Microsoft's Azure too. May it be about the region?
推荐答案
事实证明，情况有防火墙也。当我添加入站规则到Windows Server 2008实例的防火墙的问题解决了。
It turns out that instances have firewall also. When I add inbound rule to windows server 2008 instance's firewall the problem resolved.
