我刚买了一个IP Camera，在家里的LAN查看没有问题，不过不能通过Internet查看。我设置步骤如下，请高手们帮我参谋一下。

1. Set up IP camera to a local static IP, such as 192.168.0.34 with a port number 1234
2. Set up DNS Server to my ISP DNS server address
3. Create a DNS account in dyndns.com to point to my public static IP address, web link is like ipcam.webhop.biz
4. Configure my Dlink router DSL-G604T to create a virtual server to port forward http traffic in port 1234 to my IP Camera\'s IP address 192.168.0.34.
5. Open DMZ to only allow 192.168.0.34 be exposed to internet

Then I tried view my ip camera through http://ipcam.webhop.biz:1234, but I could not be able to view it.

在这过程中，我肯定错过某一个步骤，恳请大家帮我参详参详 .
