Dear Experts,

I want to connect remotely a s7-319F and a VPN (OpenVPN with router 3g Teltonika RUT500). I connect VPN through TUN configuration. I can acces to the web server of the PLC but TIA Portal V13 can not detect it. I have used a tool to verify that I can access to the port 102.

Can anybody help me?

Thank you for your help.

Best Regards!

hi stsness,

what means "TIA can not detect it"?

How do you try to connect?

regards,

Do you have the PLC in the TIA project? I dont think you can find the plc with accessible devices if you dont have a Siemens vpn router. 

Hello,

please note:

Layer 2 protocols and features (like "Accessible devices") will NOT work with VPN.

VPN is Layer 3!!

Then, are routers like Ewon different to this? 

Thank you for your answers.

Hello stsness

we used Ewon devices  in past projects but accessible nodes didn´t work.

It is as Pittiplatsch said. You have to know the IP of the PLC but if you have the project then you have everything you need.

Finally I have resolved the problem. I have configured the VPN Server as TAP bridged and I have disabled DHCP. 

Thanks to everyone.

I did the same, except the DHCP server (I didn't disable it), and it works great!
