I'm forwarding all ports. I've only enabled ip_forward and compiled my kernel with
"advanced router" on. Also configured "route" to have both networks.

It outputs "System error 51: Remote computer not available"

I didn't mentioned it but I have in linBox's smb.conf:
        netbios name = linBox

Sorry, I missed a "both" ("... _both_ boxes..."). What I meant was, if I configure
the machines to have a common network (say 192.168.28. ) , replacing the mentioned
configuration for a common network between linBox and ntBox (this network is also
IP over ATM), putting
        hosts allow = 192.168.28.
        hosts deny = ALL
        interfaces = 192.168.28.72/24
        bind interfaces only = Yes

on the linBox; it all works fine.
But with regard to your first question, if I try

I've not told you the complete picture.
To be more specific I have more than one gateway (with same OS configuration)

-------           ----------           ----------          ------
|Linux|-----------|Gateway1|-----------|Gateway2|----------| NT |
-------           ----------           ----------          ------
192.168.32.72   192.168.32.122       192.168.31.128    192.168.31.81
(linBox)        192.168.30.122       192.168.30.128      (ntBox)

ntBox has Gateway2 for network 32 and linBox has Gateway1 for net 31.
The forwarding, as you can see is done by the gateways in net 30.
All the networks are IP over ATM (so no broadcasts).
If I use tcpdump in the interface for network 30 in Gateway2 I can see the udp
connections for netbios. (regarding you first question)

Thanks for your interest
