Hi all, this: > Am 14.08.2023 um 13:32 schrieb Odhiambo Washington <odhiambo@gmail.com>: > em1 is NOT a bridge member.

In that case you must move the IP address from em1 to em1bridge. Like so: ifconfig_em1="-tso -lro -txcsum -rxcsum up" cloned_interfaces="bridge0 tap0 tap1 tap2 tap3" ifconfig_bridge0_name="em1bridge" ifconfig_em1bridge="addm em1 addm tap0 addm tap1 addm tap2 addm tap3 up" ifconfig_em1bridge_alias0="inet w.x.y.z netmask 255.255.255.0" Again: a bridge member interface must not have an IP address. Which directly leads to your last question: > One last question for today (although I should just go and RTFM): Do I really need several tap devices? Can't I just have all my VMs on tap0? Each with it's own IP in that range? You do need one tap interface per VM but these are just "virtual ethernet cables" plugged into a "virtual switch" (em1bridge). So they need not and *must* not have an IP address configured on the host side. Just create them and add them to the bridge. All IP configuration is done in the VM guest and should match the network connected to em1, of course. HTH, Patrick -- punkt.de GmbH Patrick M.
