I have a 4-port ethernet card, and have assigned one of the NICs to the Orange zone, however it’s not actually connected to anything physically.
At the moment, I’d like to add a bastion SSH server and place it into the Orange zone. I want the bastion to be a qemu VM running on my IPFire host directly through libvirt. But because there’s no carrier signal due to lack of real physical connection, my orange0 link shows orange0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN, and this is what is causing me to encounter error: Unable to add bridge orange0 port vnet10: Operation not supported when I try to start my defined host through virsh start.
I’ve also tried to add a dummy interface that’s enslaved to orange0 with:
ip link add name dummy-orange type dummy
ip link set dummy-orange up
ip link set dummy-orange master orange0
But that last command fails with RTNETLINK answers: Operation not supported, presumably because IPFire doesn’t let you manage zones in an ad-hoc manner like that (not 100% sure)?
If any more experienced users can point me in the right direction, that’ll be much appreciated.
