Hello,

I have IPC277E (IP:192.168.121.71, M: 255.255.255.0, GW: 192.168.121.254) behind the SCALANCE S615 (IP:192.168.121.254, M:255.255.255.0).

From Web Based Management of S615 i can ping google.com. But from IPC i haven't access to internet. Also i tried to disable Firewall, but without success.

Do you have some ideas what should be set-up next?

Thanks in advance for you comments.

Dear Jan,

you need to define a route through your SCALANCE device from the internal network to the external network.

See SCALANCE S615 Web based Management Manual chapter 4.4.10 at https://support.industry.siemens.com/cs/ww/en/view/109751632.

You may also have a look at the application example "Configuration of Routing in Industrial Networks" chapter 1.2.4 at https://support.industry.siemens.com/cs/ww/en/view/109755344.

Further questions regarding network configuration may be better in the Forum for Communication / Networks.

Thank you very much xnor for idea,

i tried configure routes, but  i can't reach the internet still.

From router is possible ping google.com, but from local internal subnet i can't. 

See, attached pictures please.

Solved by NAT Enable Masquerading for external subnet.

After enable firewall is also necessary accept IP rules for ports udp 53 (dns), tcp 80 (http) and tcp 443 (https)

Thank you.

hey Jan,

Can you explain this solution step by step with pictures ?
