Hello All,

I have a CPU 1513-1PN and a scalance S615.

I want to make modification on the  CPU from my office with TIA portal.

The Scalance is connected to the IT Network (External VLan 2) and to the CPU (Internal VLAN 1, private adress).

Scalance is OK, I can ping the scalance from my office (same network).

Now I don't  know how to be onLine with TIA Portal  from my office, TIA portal try to connect the CPU local adress  .

Can you help me.

Split from Remote connect via VPN with Scalance S615.

Hello

do you have set the IP Adress of the Scalance in your PLC as Router/Gateway?

Its nessesary because then the IP Packages reach the PLC from your PC but they will not find the was back.

can you ping the PLC? If not this could also be the same issue.

If you can reach the PLC with Ping and the Port 102 is not blocked then its there is nothing to do special to get access to the PLC from TIA Portal.

hello everybody,

I solve my problem:

1. I activate the router/gateway on my plc (private scalance adress) VLAN1 (int)

2. In the Scalance, i create a new source NAPT on vlan2 (EXT) with:

            - destination IP TCP (IP adress of my scalance on IT network) port 102

            - translation destination IP (IP adress of my PLC in the private network) port 102

3. On Firewall, i create a IP service that i name "PG functions"

            - Transport TCP

            - Source range (*)

            - Port 102

4. I create in the Firewall a IP rules from vlan2 to vlan1 with service "PG functions"

Thanks at all for your Help
