I'm fairly new to Raspberry Pi and networking, but learning.
I have a 3D printer with an ethernet connection, the RepRapPro Ormerod 2.
I'd like to move this to somewhere there is no ethernet. But there is still Wifi.
I was hoping to use the Pi to make some kind of bridge between the wifi and the ethernet port on the 3D printer.
I hope to preserve IP addresses, so I think a 'bridge' is better than NAT.
I've blindly followed this guide: https://www.raspberrypi.org/documentati ... s-point.md
And it seemed to work, except the wrong way around - the guide assumes that the internet and DHCP is via ethernet cable, and that these should be shared via Wifi hub created within the Pi.
I want the opposite- the internet and DHCP are supplied via the existing broadband Wifi hub, but I want to use the Pi to turn the Wifi signal into an ethernet cable signal to and from the 3D printer.
I followed the guide again from the top of the page, but I replaced every reference to 'wlan0' with 'eth0', and vice versa.
I get as far as 'sudo brctl addif br0 eth0' (but as 'sudo brctl addif br0 wlan0' in my swapped version), but the Pi gives an error that the bridge already has an entry.
So, please can anyone help?
-How can I clear the bridge file, so I can write 'sudo brctl addif br0 wlan0' to it? Perhaps that will have errors further on though..
-Or even better, can anyone supply step by step instructions from where I am now, which is a partial way through the guide? The guide above is confusing when it says "Follow the instructions above to set up the hostapd.conf file"- how far above should I go?!
