Hello!

I have problem with communication between PC to CMR on VPN tunel 

I use this solution Setting up a Secure VPN Connection between a PC and LOGO! 8

My CMR 2020 

Activated firmware version V2.1.5

Bootstrap version V1.1.4

Mobile wireless module version 13.00.106

Connection established : YES

Connection to data service established : Yes (GPRS)

When CMR logs into the mobile network I have public IP 

I use Automatic time-of-day synchronization, via NTP works fine

Then I Setting up remote access according to point 2.3 in this document

I don't use DynDNS so I modify vpnpeer.conf by replace the DynDNS entry in line 4 by my public IP address.

Save file cmr.ovpn 

On PC I use OpenVPN v 2.4.6

import my cmr.ovpn file and connect 

The OpenVPN client never establishes a VPN tunnel to LOGO! CMR bytes is send but not receive

I'm doing something wrong or problem is in the other things

Regards

Hello Miszcz

According to the instructions from the document:

If  CMR has  logged  in successfully  in the  mobile  network  connection, the provider  will  assign  a public  IP  address  to  the  SIM card.  You can  view  the assigned IP  address  in the  web-based management of  CMR  in  "WAN > Overview". Replace the DynDNS  entry  in  line  4  by  this  public  IP  address.

Is this the IP address that you enter in line 4?  Because you said that you entered your public IP address. You mean your routers external IP address? If so, change the address with the one from the SIM card.

Hi 

thanks for reply Yes of course I use IP from SIM card.

Is other way to get acces (GSM network) to WBM without VPN tunel?? 

Hi,

I'm stuck at the same point... Have you resolved your problem ?

Thanks !
