Hello,
I have just upgraded one of my servers to 2.6.15 and noticed that
computser are no longer able to browse "Network Neighbourhood".
Packets sended by workstations (for example 192.168.0.3) to the broadcast
address were ignored:
14:31:56.027354 IP 192.168.0.3.138 > 192.168.0.255.138: NBT UDP PACKET(138)
14:31:58.027459 IP 192.168.0.3.138 > 192.168.0.255.138: NBT UDP PACKET(138)
14:31:58.027584 IP 192.168.0.3.138 > 192.168.0.255.138: NBT UDP PACKET(138)
What is strange that I solved this problem by recompiling and booting
kernel without ip_conntrack_netbios_ns enabled. Now everything works
fine. I thought that it should only handle UDP packets to port 137...
Best regards,
Krzysztof Olędzki

It does, your problem must be related to something else. Can you verify
that enabling the helper again causes the problem to reoccur?
