There is a step by step description for the VPN configuration.

Hi Symfairy

well. I followed all steps from manual. but don't work. on a diagnosis that i made, i found on the module the external IP is not same public IP. someone know why happen this?

Hi GTami,

how was your PC connected wjen you did this ping?

Btw, for which side of your network do you have the DDNS?

I think you need static public IP address from the mobile network operator of the SIM card of the SCALANCE M 874-3 so that can also be accessed from the internet.
