Since some time ago, I cannot connect to my NAS outside my LAN using my external IP. I used to connect using FTP/SFTP without any problem. Now, I can connect to using my externl IP but ony when I am within my LAN. Strangely, when I ping to my external IP i get 0% of lost packages, so it seems to work. I am not a networking master, so i'm a bit puzzles. Can anyone help? My setup is a Conceptronic CH3HNAS connect to a Cisco EPC3825 modem.
Thank you so much!
