no real ip addresses

[Administrador de Redes]

hello 

I have a remote LAN using no real IP addresses behind a freebsd triyng to
connect my samba server on Linux , I have my samba server running WINS .
PC's on remote LAN are using my Linux like WINS server , the problem is I
can't see the samba server , all pc's can do telnet and other services .
I have tested real Ip addreses before and it works , what's hapenning ?

Thanks in advance

Ernesto
