[Strrav]

QNAP TS 251 recently bought and impossible to share folders to anyone
I tried many ways ans saw many Tuto.
I can reach all my folder .I can see my folders (video music etc...) everywhere outside my personal Wifi (abroad, Wifi, and 4G)
but I can not share to anyone. I tried many way (link/email/NAS account ) . the message for the recipient is they "can not reach the server"
file Station sharing Link adress are like this http://192.168....8080/share cgi .... port 8080 is opened .
I am on MacosX el capitan .Tried with Safari , Firefox and Chrome etc;.. 10 days trying .
Help me please

192.168.x.x is a private IP range .. no wonder the links don't work

switch it from IP address to domain name (your myqnapcloud name)

Thank you.I tried many way , link like https://www.myqnapcloud.com/smartshare/61gfk..etc.... or link like https://FRLQNP.myqnapcloud.com/share.cg ... impossible to reach the server
It worked one time yesterday when it generate an address like this https://192.168.1.17/share.cgi?ssid=0qj etc... seem to be OK
What do you think ?

[dolbyman]

the second link should work, if you have setup forwarding correctly in your router

3rd one is again a private ip and thus will not work


or go to here:
https://www.iplocation.net/

and find out your external ip and replace the private one (192.168.x.y)

both ways only work if you have a dedicated ipv4 ... if your isp does some Carrier grade NAT ...it will not work

One more point: On many consumer grade router, the NAT configuration does not allow accessing the LAN trough the external IP (or name) by doing NAT loopback from the same LAN.

Thank you for your answer.
As you see, I am not an expert and I don't understand all the NAT and LAN stuff, , I understand that the address like 192. etc... is internal, so it don t work outside
How can I "setup forwarding correctly in my router" ? I just turn the red Port in my box and turn it to green (port 80 and 463 )
I wons I can access A LAN and NAT menu in my box , but don t know what to do...
