I have 4 LOGO 8 communicating with each other via a network switch.

LOGO 1-3 are LOGO 8 standard while LOGO 4 is LOGO 8 FS04.

The CMR2020 will also connected to the same switch.

I Got a CMR2020 and I want to use it for SMS control and make use of its VPN for remote support when I am not at home.

For SMS control, I don't have problem with that as I have already forwarded all what need to be Control by SMS in LOGO 1-3 to LOGO 4 which I am putting its IP address in the CMR2020 for SMS control.

The WEB SERVER control for LOGO 1-3 are also forwarded to LOGO 4 using network inputs and outputs for control which is working perfectly now.

My main issue is will it be possible for me to download/upload from all the four LOGO when connected to the CMR2020 remotely via VPN.

I know I am going specify the CMR2020 as the gateway in all the 4 LOGOs, what I don't know is if I can be able to access the 4 LOGOs from the CMR2020 VPN.

see below my IP addresses configuration.

CMR2020 IP Address: 192.168.1.43

CMR2020 SUBNET MASK 255.255.255.0

LOGO 1 IP Address:192.168.1.44

LOGO 1 GATEWAY: 192.168.1.43

LOGO 1 SUBNET MASK: 255.255.255.0

LOGO 2 IP Address:192.168.1.45

LOGO 2 GATEWAY: 192.168.1.43

LOGO 2 SUBNET MASK: 255.255.255.0

LOGO 3 IP Address:192.168.1.46

LOGO 3 GATEWAY: 192.168.1.43

LOGO 3 SUBNET MASK: 255.255.255.0

LOGO 4 IP Address:192.168.1.47

LOGO 4 GATEWAY: 192.168.1.43

LOGO 4 SUBNET MASK: 255.255.255.0

thanks for the response.

I think I have a solution to my problem.

since I will have access to the web server of the CMR2020 remotely and all the 4 LOGO are in the same network with the CMR2020, I can easily change the IP address of the LOGO in CMR2020 to the one I want to have access to and monitor it.

AM I right with this assumption?
