Hello friends, I have a problem and hope for help.
I have a laser printer that still works very well (and still has toner). The printer was connected to a WiFi print server via a power cable. Now the print server is broken. I only have WiFi in the house.
I still have a TP-Link TL-WR802N V4 with OpenWrt.
I manage to connect the WR802 to the WiFi (Fritzbox), either with DHCP or static IP, and can also ping them.
But I can't manage to configure the LAN output of the WR802N so that it forwards the data to the printer.
The WiFi has 192.168.178.70 (DHCP or fixed) - the printer
has a fixed IP (no DHCP) 192.168.178.15.
I would be very happy if someone could help me.
Many thanks - Greetings from Germany Wolfgang
It is not possible to directly bridge a wifi uplink --> wifi and/or ethernet downlink. This is the result of the way the wifi standards were developed, not OpenWrt specific.
You probably want to use something like relayd.
If your upstream router is running OpenWrt, you could use WDS or mesh (802.11s) instead. But if not, relayd will likely be the preferred method.
The other approach is to use the system as a standard routed client. This would likely make printing more complex, though.

Thanks .. !
For a standard routed client the printer must be in a different subnet. Then you can either forward ports to it (and treat the Wr802's address on the house network as the printer) or set up symmetric routing, which requires installing a static route in the house's main router so it is aware of the printer network.
Either way you will need to configure the printer's IP into your PCs manually.

Hello,
Thank you for the information.
Everything is running really well now.
Set up the WR802N using "relayd". All PCs access the printer via a fixed IP.
So I don't have to throw away the printer that is still working.
Best wishes from Germany, Wolfgang
