Port 137 is the netbios port. It could just be searching for other windows machines on your network. Regards, -Roberto -- Roberto C.

Yes, we have many Windows machine on local lan, you can see the log said many local lan IP using port 137 to boradcast (192.168.0.255) , so that shorewall receive the boardcast message is correctly ?

PROTO=UDP SPT=137 DPT=137 (and the port 138 packets) are just the Microsoft NetBIOS stuff working out what is on the network. In short, all the machines broadcast messages, work out ''who else is out there'', and hold an election to decide who is going to be the ''browse master'' for a workgroup. When you go into ''Network Neighbourhood'', your machine gets a list of other machines from the browse masters for each workgroup on the network. Yes, as you can see, it involves a lot of broadcast traffic ! I similar thing happens with mDNS (Multicast DNS, aka ZeroConf, aka Bonjour or Rendevous in the Apple world) on port 5353 for ''more modern'' networking. There is also some DHCP traffic (port 67 & 68). I''m not sure what ports 1124 and 1357 are, but from what I have found on the net I don''t think they are anything to be worried about. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
