Forward (share) network to a bridged interface of 3 adapters
I have a network like this:
network structure picture
I need to configure the Kylin laptop to let other clients(PC, phones) access internet. I have 3 USB ethernet adapter (enx000ec6c5afc1, enx00e04c68009b, enx00e04ca01003) pluged in the Kylin. I want all the clients to be in the same subnet (to use RPI as second gateway).
So I tried to bridge the 3 USB eth adapter together as br-lan, and configure dhcp and iptables to it.
