描述:
One last thing before I continue, the client must be able to reach the server by its actual IP address. You cannot use DCOM through firewalls that do address translation (i.e. where a client connects to virtual address 198.252.145.1 that the firewall maps transparently to the server's actual address of, say, 192.100.81.101). This is because DCOM stores raw IP addresses in the interface marshaling packets and if the client cannot connect to the address specified in the packet, it won't work.

读了msdn:Marc Levy Microsoft Corporation April 23, 1999的COM Internet Services,感觉已经不需要顾及这个问题了，cis似乎能够穿过绝大多数的firewall，我的问题是,我应该相信谁？按时间来说，似乎是后者，但是后者的文章又让读者去看前者，我很犹豫；请做过相关问题的大佬回答
