setting up masquerading, DNS + Samba server

[brazilian_joe]

All right, I have set up Masquerading in my linux box for my Office. now the laptop accesses the internet through it. I have also set up djbdns as a DNS caching service and internal server. But, after that, my laptop can't see the samba server anymore. It is like this:

laptop
(10.0.0.20)
|

(eth1 10.0.0.1)
linux server (masquerading, DNS server, Samba Server)
(eth0 DHCP, usually 192.168.1.1
