Hi

How do i remotly connect to a Siemens S7-1200 over an 4g modem?

I have a set up the PLC with static ip address: 192.168.1.10 and Router 192.168.1.1 (modem`s lan)
The modem is set up with static LAN ip: 192.168.1.1
The modem has an static WAN ip: 37.xxx.xxx.xxx

In the modem i have set up an port forwarding on port 102 -> to the PLC adress.

On other PLC types i just connect to the WAN IP to the modem and then get remotly access to the PLC. 
But I cant seem to find the place to put in the WAN IP for connectiong in the TIA portal?

Does anyone have a tip?

I know port forwarding is not a secure solution, but this is only for a quick change in the program.
The modem is removed after the changes have been done.

Thanks in advanced.
