netdev user,restrict=on prevents forwarded ports from being accessed
from other systems
Status in QEMU:
I've got a guest only network and I'm wanting to access SSH on one of the
I'm using -netdev user,id=usernet0,hostfwd=tcp::2222-:22,restrict=yes -device
to forward 2222 to 22 in the guest.
The docs state:
If this option is enabled, the guest will be isolated, i.e. it
will not be able to contact the host and no guest IP packets will be
routed over the host to the outside. This option does not affect any
explicitly set forwarding rules.
However, with restrict=on, the forwarded port is only accessible from the
host. Other systems receive no data.
This was tested with qemu 2.8. Changelog for 2.9 doesn't mention any
(relevant) user networking changes, so that should also fail.
