我假设，因为你有问题，传入连接防火墙问题。

I am assuming because of firewall issues you have problems with an incoming connection.

在这种情况下，以解决该问题的常用方法是

In such a scenario a common way to solve the problem is.

有从中使用服务请求的 A 也许 GetNextNotification 轮询服务器一个单独的线程 在这方面应该有一个较高的超时时间。 在服务器端时的 A 的处理方法不会返回，直到有一些服务器想要传达的客户端 当 A 返回客户端处理的通知，并让另一个 A 的要求。 Have a separate thread from which you poll the server using the service request A maybe GetNextNotification This connection should have a high timeout. On the server side when A is processed the method doesn't return until there is something server wants to convey to the client Once A returns the client processes the notification and makes another A request.
