So I understand that you can configure a PI to act as a bridge - going from wifi to ethernet port, etc. My question is a bit different - and not sure if I can do it.
At a customer site we have multiple IPADs that access a customer wireless network. We also have a PI accessing the same wireless network. The client wants to know if we can make the PI act as our own internal wifi-network (non published SSID) - and have it connect to their WIFI network at the same time. Basically acting as a wifi-gateway - but not using the ethernet port at all.
Theoretically this seems possible - but it also means the pi probably has to act as DHCP server as well (no big deal).
