Dual Homed Samba Server Problem

[Tacio AGSantos]

Hi,

There may be a simple mistake of mine, but i just can't figure it out:
 I tryed to play around with options but with no success. 
If you could help me i'll be grateful, so that's is my environment:

- there are 2 networks: 172.16.0.0/255.255.255.0 and 172.16.1.0/255.255.255.0
- i've setup up a Linux box with 2 cards : eth0 172.16.0.2 and eth1 172.16.1.2
- i have Win9x clients on both networks, ip forwarding is enabled on the Linux
box so i can ping through it.
- I have only one group/domain called PSMI, and i would like to use it for
both networks.
- samba version is 2.0.4b and a have the following smb.conf

#======================= Global Settings =================================
[global]
 character set = ISO8859-1
 debug level = 10
 bind interfaces only = yes
 hosts allow = 172.16. , 127.0.0.1
 interfaces = 172.16.0.2/24 172.16.1.2/24 127.0.0.1/255.0.0.0
 deadtime = 15
 netbios name = ATILA
 workgroup = PSMI
 server string = Servidor Atila - Samba Server
 max log size = 50
 security = user
 local master = yes
 os level = 33
 domain master = yes 
 wins support = yes
 dns proxy = no 
 preferred master = yes
 domain logons = yes
 logon script = %U.bat
 wins support = yes
 name resolve order = wins bcast 
 ... --//--

- Besides, i use dhcpd to configure my Win9x machines, and there a set up
netbios-name-servers to be 172.16.0.2 and 172.16.1.2 respectvely;

THE PROBLEM IS: Although i get the complete browse list with all machines a
cannot access a machine that's not on the same network. Also, doing
nmblookup i cannot find names from the net 172.16.1.0 , but from the other
network it's OK.

Some questions are:
1. Do i need to set up 2 groups , one for each network?
2. Will i have 2 wins' (nmbds) running, or i can use just one ?

Thanks a lot for your attention,

Tacio
