Hi, the remote access to the Siemens Logo PLC doesn't work.

I have the RUT230 with a SIM-Card with a public IP-Adress

At the LAN-Port is a PLC with the IP-adress 192.168.1.3.

I made a Port-Forwarding to the IP 192.168.1.3 Port 8080, which is the Webserver-Port of the PLC.

I don't know, why, but it don't work.

If i am making a general portforwarding to the IP 192.168.1.1 i can open the WebUi from extern.

I have also an other Modem, here i just make one portforwarding to Port 8080 and it works.

100.96.228.17 goes to the WebUi (IP: 192.168.1.1)

100.96.228.17:8080 goes to the webinterface from the Logo-PLC (IP: 192.168.1.3:8080)

Can anywone help me? 

Greetings Dennis

Hello, Dennis

Can you double check if 100.96.228.17 IP is your public IP address? Just go to ping.eu and check if the field "Your IP is" matches the IP you see in your routers Overview > WAN section.

Hi if i am connected with the RUT230 and go online over this modem and check on ping.eu my IP is 18.197.48.88. 

The operator of the SIM-cards is 1NCE and has an VPN and fixed IPs.

As i say, at an other modem, it works very fine without doing anything, only one portforwarding-rule.

Are you trying to access the device from internet? Because in that situation you should connect through public IP, in this case 18.197.48.88, but in order to do that, your provider should forward the traffic  18.197.48.88:8080 to 100.96.228.17:8080 and then you should forward 8080 to 192.168.1.3.

Only way to make your configuration work is to try reaching your device through 18.197.48.88:8080 from the device in the same subnet for example 18.197.48.89.

You can read more on that https://wiki.teltonika.lt/view/Private_and_Public_IP_Addresses

Also, does the other router also have local IP address or has a true Public IP? Maybe you could check?

Hello,

have you managed to get it working, because I'm trying to do a simmilar thing?

I have a SIM Card from 1nce and I am able to ping the WAN IP shown on the Webinterface on my RUT 240 one I'm connected to the VPN provided by 1nce but 1 can't get any further than that.

If you did manage to get it working, can you please tell me what your solution was?

Hi, ist works if you enable the remote access. I also had to deactivate the "RFC1918 filter".
