wcf 关于 wsDualHttpBinding 回调

haroun 2009-02-20 11:54:51

我采用的wsDualHttpBinding绑定来实现回调的,但是在本机测试可以的程序,把服务端部署到服务器后,客户端就不能访问回调服务了.会出现超时现象.
不知各位有没有遇到这种情况.我试着从服务端ping客户端,ping不通,可能就是因为这个不能实现双通道吧?但是用tcp协议是可以,这容易理解,但这不是我要的结果.我希望可以用iis作为服务端,实现双通道,希望各位给点策略!

楼主：
我现在比你好点，能够单向成功（wsDualHttpBinding）,就是不能够回调。
开始也出现逆刚才的问题，我把用localhost的地方换成了具体的ip地址就可以实现单向功能了。

最近也遇到这个问题，挺郁闷的。防火墙关掉，给客户端所使用的端口添加所用的端口，也可以。
帮顶，请高手解决这个问题哈
