Howto bridge eth0 with wlan?

[rfhenke69]

I'm using my setup with my android phone via USB and this works great for as it should as Wifi hot-spot, but I have a Ethernet only device I was hoping to plug into my raspberry's eth0 port. I kinda thought this would work automatic, but it didn't and I also can't find a config setting...

I did manage using the interface to switch eth0 from DHCP to static and enabled a DHCP server with a new range and this worked to provide my device on eth0 with a IP via DHCP from that range... but traffic is not routed out via USB...

I don't mind having a different DHCP range on eth0 and WLAN, but I guess simply bridging eth0 and WLAN would be the perfect solution.

Any advise?

Hi, this is a suggestion.
You can connect an adapter usb3/rj45 . it's directly recognized. https://www.amazon.fr/gp/product/B00MYTSN18/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.8.26  netmask 255.255.255.0  broadcast 192.168.8.255

eth1: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        ether 00:0e:c6:70:68:1c  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

The difficulty remains in the configuration.

thanks, but I have no clue how this would solve my problem? I don't need a 2nd ethernet adapter

I just want traffic from my build-in ethernet eth0 been routed via my cell (usb) the same way wifi traffic is routed out...

Ether I assume a routing issue or by bridging wifi and ethernet... which I tried but failed
