VPN - Use Ewon in a single subnet

Hi, I am using an Ewon Cosy for remote access to a S7-1200 that works perfectly with the PLC on it’s own subnet as you can’t have the WAN & LAN subnets in the same domain.
Moving on…
Do you have a gateway that can have the WAN & LAN subnets in the same domain? I’m thinking specifically of several existing S7-315 PLC’s that are sat on a factory network.
Many thanks.

There is not a special gateway for this, but I do have a trick that you can use with the Cosy to get access to devices in the same subnet as your internet connection comes from:

Please note that you will only be able to reach the Web interface over the WAN address now.
