[Samba] File sharing and subnets

[Julien VINCENT]

Hello,

i'm trying to setup a samba file server, but i need your advices.

the goal of my setup is to share a folder from a linux server to windows 
clients (for the moment i do my tests using smbclient on linux hosts).

The server and the client are on different subnets, but they can ping 
themselves.

Samba is installed on the server (192.168.0.1/24), and smbclient is 
available on the client (192.168.1.1/24), connected thru a gateway.

the problem is that i can't connect to the server from another subnet 
via samba.

here is smb.conf from the server (taken from the o'reilly book 'using 
samba'):

[global]
	netbios name = server
	workgroup = GARDEN
	wins support = yes
	dns proxy = yes
[test]
	comment = For testing only, please
	path = /export/tmp
	read only = no

server side:
[root at server etc]# ping client
PING client (192.168.1.1) 56(84) bytes of data.
64 bytes from client (192.168.1.1): icmp_seq=1 ttl=63 time=0.924 ms

[root at server etc]# smbclient -L server -N
Anonymous login successful
Domain=[GARDEN] OS=[Unix] Server=[Samba 3.0.37]

	IPC$            IPC       IPC Service (Samba 3.0.37)
...

[root at server etc]# iptables -L

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

client side:
[root at client]# ping server
PING server (192.168.0.1) 56(84) bytes of data.

[root at client]# smbclient -L server -N
Connection to hercule failed (Error NT_STATUS_UNSUCCESSFUL)

when i connect from another client (located on the server's subnet, ie 
192.168.0.2/24), it works:

-bash-3.2$ smbclient -L server -N
Anonymous login successful
Domain=[GARDEN] OS=[Unix] Server=[Samba 3.0.37]

	Sharename       Type      Comment
	---------       ----      -------
	test            Disk      For testing only, please
	IPC$            IPC       IPC Service (Samba 3.0.37)
...

To resume my problem, i can not connect to a samba server from a client 
located on another subnet.
Thank for your help.
