I have seen continually this message in IPFilter log file.

Jul  2 20:30:33 nas3a ipmon[1753]: [ID 702911 local0.warning] 20:30:32.565073 2x e1000g4 @0:11 b,138 ->,138 PR udp len 20 250 IN low-ttl

The port 138 belongs netbios according to /etc/services file:

# cat /etc/services | grep 138
netbios-dgm     138/tcp                         # NETBIOS Datagram Service
netbios-dgm     138/udp                         # NETBIOS Datagram Service

So I wondering what the message is trying to do. Is it a broadcast one? Blocking it will have any impact?
