Q-Application don't connect while on WAN/LTE, when on LAN all works well

[jsvoboda1]

Hi all,
may I ask you for an advice why I cannot access my NAS from WAN/LTE? When connected at home to LAN/WiFi all application are able to connect NAS and access data on NAS. When on LTE/WAN I cannot reach out NAS.

PS: Few days ago it worked without issues, the only thing changed was new firmware 4.3.6.0923 with TS-251B and bigger HDD from WDRed 4TB to WDRed 8TB. I tried to reset NAS erasing all data and configuring all from beginning...still didn't help without implementing security settings.

Thank you for your help

if your nas is accessible via wan then that means it is exposed to the internet (bad idea..see all the hacked unit threads)

so are you sure it was accessible (and by that you mean what parts?) from wan?
