anybody could help me with my ddns which dont work from remote admin.I own a thecus nas n1200 My ip is dynamic My router is sagem fast 1500wg..Please someone help me..I try to set up ddns about 3 months but nothing... Sorry for my english...I am greek ;D I have tried also with no-ip...not only with dyndns.org
Dracos : I didn't see your router wan administration access in your picture but however both of your device are associated to dyndns. Only one device must be connected to it (your router is the better choice). Secondly, you ve put your nas into your router dmz port, if you do this you don't have to forward anything : all the wan traffic going to your router will be redirected to your nas automatically (so it can be vulnerable to hack). Port forwarding is only used when you want to redirect some ports to it (our case).
Finally, you have not blocked the ping access to your router, so you can test it to the dyndns working: ping myDynDnsUrl.com
I was talking about pinging my dydns address actually... but I just tried to ping myself (ip address) from network-tools.com and it timed out, it comes up with the information-area/isp but under that it just lists Timed Out with average time over 10 pings: 0ms
It doesn't matter if you cannot ping your dyndns address (disable this option on network-tools form)... Set the ports (http/https/ftp) forwarding on your router and connect directly to the service you want.
Once connected, you have all the time required to check how to enable the wan ping as well.
If you nas is using http, I suggest you start setting that service on your router.
Reminder : http= port 80, https = port 443, ftp = ports 20 (!) AND port 21. If you are not using default port for ftp, consider forwarding port 20 AND the port you selected.
If you cannot connect to your nas using http, you should double check your router manual.
