Configure OpenWrt as old fashion HUB like

Installing and Using OpenWrt
1

Hello.
I would like to configure the OpenWRT as an old fashion Hub like, i.e. to sniff traffic without using IPv4, just connecting the RJ-45.
Would you please help me?

there's a package mirroring option somewhere, at least in openwrt 19....

Thank you very much. I've found this: https://github.com/mmaraya/port-mirroring, I'll try it!

sounds like nftables can also do that: https://wiki.nftables.org/wiki-nftables/index.php/Duplicating_packets

Great, thanks @Pico, I'll test that too!
