Forward netbios broadcast packages
 

In my LAN i have a RH9-box running with arp-routing (parprouted). Both sides of is on the same subnet (192.168.0.0/24). How can i make Netbios-broadcast packages pass trough it?

I did some iptableing without any progress.

pkts bytes target prot opt in out source destination
0 0 udp -- eth0 atml0 0.0.0.0/0 0.0.0.0/0 udp dpt:138
0 0 udp -- eth0 atml0 0.0.0.0/0 0.0.0.0/0 udp dpt:137
0 0 udp -- atml0 eth0 0.0.0.0/0 0.0.0.0/0 udp dpt:138
0 0 udp -- atm0 eth0 0.0.0.0/0 0.0.0.0/0 udp dpt:137

Btw, the box functions as a wireless AP.
