Wi-fi in Access Point mode
#1
Hi Armin, before wasting hours in testing, I don't remember if I can connect via AccessPoint to the Gateway and then I can ping an instrument on the Eth0 network.
Once connected to the access point, I can ping the IP address of Eth0 but not the instrument on the same network as the Eth0 port.
Do I need to enter any rules?
Could this thing be done in both the netPI and an Edge Gateway?
Thanks.

To be honest I am not a networking specialist so I don't know what all is needed in all details.

I remember I had tested such a constellation once and one thing I remember was to enable in the firewall setting to set the eth0 interface to status "trusted". Then with an active access point you should be able to ping devices in the eth0 subnet from a PC for example that is connected to this access point as a client.

Thanks Armin, yes, the default firewall setting is already set to Trusted.

Hi Armin, I found an old question from a customer, it seems that the IP addresses set in the access point must be completely different from those set in the Eth0 port.
So if the Eth0 port is set as IP: 192.168.2.1 and the SubNet: 255.255.255.0 the Wifi Access Point port "must" be IP: 17.100.4.16 Subnet: 255.255.0.0.
This way it works but I don't know why, my skills stop there, as a client of mine says: I'm a technician up to the curve... :-)
Thanks as always for your availability.

Well, thank you Renato for letting us all know that it works the way I described it.

Two physical interfaces with the very same IP network address room/pool will never work in general. This has nothing to do with netPI and wifi and eth0 doing parallel communications. This is just basic IP networking practice and knowledge in my eyes.
