LABEL DESCRIPTION
# This is log number five.
time The log was generated on June 8, 2004 at 5:58 and 20 seconds AM.
source The log was generated due to a NetBIOS packet sent from IP address 172.21.4.187 port
137.
destination The NetBIOS packet was sent to the 172.21.255.255 subnet port 137. This was a
NetBIOS UDP broadcast packet meant to discover devices on the network.
notes The LAN-Cell blocked the packet.
message The LAN-Cell blocked the packet in accordance with the firewall’s default policy of
blocking sessions that are initiated from the WAN. “UDP” means that this was a User

WAN to the WAN or the LAN-Cell.
