I'm trying to bridge a network interface between host and guest (both Debian Buster+Bullseye+Sid) so that NAT is not needed.
If you don't incist on using /etc/network/interfaces you could also use systemd-network: /etc/systemd/network$ tail -n +1 * ==> br0.netdev <== [NetDev] Name=br0 Kind=bridge MACAddress=<MAC-OF-INT-TO-BRIDGE> ==> br0.network <== [Match] Name=br0 [Network] DHCP=yes ==> uplink.network <== [Match] Name=<INT-TO-BRIDGE> [Network] Bridge=br0 This assumes that the bridge will reseave an IP from a DHCP server.
