Dear group

I am wondering, how to solve the following problem with NetBSD:

I'd like to create a C-Class Network Net2 'insde' a NetBSD
host like this:



                           NetBSD host
                      .....................
                      .                   .
      I--------I      .     I--------I    .      I--------I
  ----I  Net1  I------------I  Net2  I-----------I  Net3  I------
      I--------I      .     I--------I    .      I--------I 
                      .                   .
                      .....................


Net1: Network with Private addresses
Net2: Network with offical addresses
Net3: our DMZ

NetBSD host: A NetBSD Firewall/NAT-Box with one interface
             into Net1 and one into Net3

The goal would be to use the addresses of Net2 as NAT source
adresses so I wouldn't need to use up alot of Net3 adress space
for that.

I guess, I'd have to use the lo(4) interface for that, wouldn't I?
But lo(4) doesn't explicitly mention such a usage.

Would it be possible to create lo1 additionally to lo0?

Has anybody built something like this?

Thanks
Chris
