Yes, for the test, when the routers are connected LAN to LAN (fig.1) berween client 1 and client 2 there is a connection.
In real conditions, one client is on a fixed point and the other is on a moving one. Due to tehnical limitations, wired connectivity between clients is not possible. This necessitates the use of a wireless connection (fig.2).The protocol by which client 1 and 2 communicate is PROFINET - the connection is based on MAC address. Routers must be completely transparent for layer 2 communication.
Is it possible and with what settings should the routers be in order to ensure such connectivity via WiFi.
