The asus manual don't tell me anything about this. 1. On the config DDNS page there is a button for Export https/ssl certificate. I have never used it and what will happen? 2. Today I reach the router or camera from remote using the vpn and http or ip without http. Should it change to https? 3. If a certificate is exported, where and how shall I use it? 4. I don't have config any ssl in the camera. Should it be when the "export" of certificate is used? Hope for help.
