DD-WRT Dynamic DNS(DDNS) Setting

DD-WRT附有DDNS的功能，預設提供Dyndns、NO-IP等較多人使所熟知的免費服務，只要填入帳號、密碼及網域名稱即可。但不知為何原因，預設的Dyndns及NO-IP在設定完成後，第一次都會成功的註冊及更新IP，但是之後每次都會出現錯誤。

Wed Jun 25 13:48:40 2008:I:INADYN: IP address for alias 'xxx.dyndns.org' needs update to 'xxx.xxx.xxx.xxx'
Wed Jun 25 13:48:40 2008:W:'RC_IP_RECV_ERROR' (0x15) updating the IPs. (it 0)
Wed Jun 25 13:54:40 2008:W:'RC_IP_RECV_ERROR' (0x15) updating the IPs. (it 1)
......

官方的文件是說要將DDNS改成Custom的模式去設定，詳細設定如下：

括弧內需做適當的修改
‧DDNS Service: Custom
‧DYNDNS Server: members.dyndns.org
‧User name: (your username)
‧Password: (your password)
‧Hostname: (your hostname registered in dyndns.org)
‧URL: /nic/update?
‧Additional DDNS Options: --dyndns_system dyndns@dyndns.org --ip_server_name checkip.dyndns.org:8245 /
If static DNS is used, use statdns@dyndns.org instead of dyndns@dyndns.org.

記得儲存起來，依此設定修改，之後就沒有出現錯誤訊息了。
