If by spoofed you mean reserved,internal adresses: be aware that you're
outside the allowed range ( (See RFC 1918)

If full and mutual trust is expected / wanted:
Hm... reading on I notice you don't use the Suse firewall filter. Why not ?

Explain. From ANYwhere implies "from internet". Surely you CAN not want that.
If you mean from LAN1 <-> LAN2 then either the above class routing will fix it
(when you use AD + properly configured DNS servers) or you may need to
specify the exact share by IPnumber (net use * \\192....\C
If both are not options you will need to find a way to relay the Netbios
broadcast(s) over the firewall. Dunno offhand how to do that (and wouldn't
want to either).
