41 Using the user mode network stack
44 By using the option ``-net user`` (default configuration if no ``-net``
45 option is specified), QEMU uses a completely user mode network stack
61 In order to check that the user mode network is working, you can ping
65 Note that ICMP traffic in general does not work with user mode
76 When using the ``'-netdev user,hostfwd=...'`` option, TCP or UDP
80 Using passt as the user mode network stack
83 passt_ can be used as a simple replacement for SLIRP (``-net user``).
85 better performance than ``-net user``, full IPv6 support and better security
