- to the outside world that the host user is permitted, and unlike
- other transports, SLiRP works without the need of root level
- privleges, setuid binaries, or SLIP devices on the host. This
- also means not every type of connection is possible, but most
- situations can be accommodated with carefully crafted slirp
- commands that can be passed along as part of the network device's

- that of a host behind a firewall that masquerades all network
