Maybe your best bet is adress-translation on the NetBSD machine (NAT).
You can get it with the ip_fil lkm.
ip_fil is the string to let archie search for...
Once you got that running, all other machines on the net can route through the
NetBSD machine and appear on the outside as the NetBSD machine.
from the man:
To change IP#'s used internally from network 10 into an
ISP provided 8 bit subnet at 188.8.131.52, the following
would be used:
map 10.0.0.0/8 -> 184.108.40.206/24
The obvious problem here is we're trying to squeeze over
16,000,000 IP addresses into a 254 address space. To
increase the scope, remapping for TCP and/or UDP, port
remapping can be used;
map 10.0.0.0/8 -> 220.127.116.11/24 portmap tcp/udp 1025:65000
which falls only 527,566 `addresses' short of the space
Tragbar ist, was nicht herunterfaellt.
