Are you saying that no machine on your LAN supports DHCP? I don't believe it. It's the default during installation for most OSes since it's simpler. > > > > 172.16.1.125.137 > > > > 172.16.1.125.138 > > > > > > If you're not using that subnet, then it's nbt > > > broadcast chatter. Yes, thats RFC 1918 class B addresses, ports 137 and 138 (Windows SMB traffic). To get rid of them, disable NetBIOS over TCP/IP in the windows client with the IPv4 address 172.16.125. You should also see a lot of 172.16.255.255 (subnet-directed broadcast), because SMB is almost totally dependent on broadcasts. I find it very annoying. They are NOT IPv6 packets. -- "Curiousity killed the cat, but for a while I was a suspect" -- Steven Wrig= ht Security Guru for Hire http://www.lightconsulting.com/~travis/ -><- GPG fingerprint: 9D3F 395A DAC5 5CCC 9066 151D 0A6B 4098 0C55 1484
