see  ipconfig(8).

that's not strictly true.  as long as you restrict your network to
plan 9 machines, it is possible to import /net from a gateway
machine and avoid sticky things like packet filtering.  there is
also ipmux (discussed in ip(3)).  i don't think ipmux has enough
rewriting (or state) to implement something like nat.
