Hello, I work at a ISP in Brazil. We have a costumer that wants to 
connect their 2 private networks(witch RISC 6000 and AIX) using the Internet.
So, I suggested the following configuration ( I know the ips are 
registered... but the costumer uses this configuration....). 

    
     (AIX 4.1)
   128.0.0.1       128.0.0.10    
      |                 |
  -------------------------- Natd => FreeBSD
                        |
                    200.248.184.y 
                        |
                 
                
                    

                     INTERNET

              
                    
                       |
                   200.250.250.y 
                       |
   -----------------------  Natd => FreeBSD
      |                |
   130.0.0.1        130.0.0.10
   (AIX 4.1)


Well, when I try to make connectios from 128 or 130 to another site at 
Internet all is OK. When I try to make connection from any site at 
internet to 128 or 130 all is ok too( I made permanent links... ). But, 
when I try to make connections from 130 to 128 using permanent links I 
got the folowing errors :

telnet 
and rlogin => the conection establishes... It prompts to me login ..  password
              ...but.. when it finish the autentication... the conection stop.
              .. It doesn't print me the shell '$'

ftp        => the conection establishes... I log...when I try one 'ls' the 
              PORT command is printed like successful... but no data arrives 
              to me.....

The most strange thing is that... I simulated situations like this... 
with FreeBSD machine using classes 10 on both sides... All worked 
perfectly....

I tried to change parameters like some_ports and use_sockets....
I really need some help... the net of the costumer is really big and 
complex.. 
I really need to put this to work.... 




Thanks... and sorry for my English
