Hello
I have a problem with using DDNS.
I'm using a SXT LTE kit router that I've inserted a SIM card into.
Now I'm using the basic settings (I've entered the card pin and have internet) but the DDNS address isn't working for me (i think). DDNS only works on the internal network but it doesn't respond from the outside.
I would like to do port-knocking from an external network (e.g. from a phone in another city) so that when i complete the steps (port-knocking) it will start the internet for e.g. 1h. in my home
I've managed to do it before from an internal network, but no packets are coming from the outside to the specified (open) ports.
Of course DDNS is enabled
I use a SIM card which has a dynamic ip address.
thank you
