It's just windblows braindamage, it likes to send netbios IP traffic to really strange IP addresses using really strange source addresses some times. Easy fix is to drop all any 138 to any 138, and any 137 to any 137, unless your fool enough to want to run netbios over the internet, in which case you'll have to allow some specifc IP's to work. > > Omachonu Ogali > Intranova Networking Group > > On Thu, 13 Jan 2000, Brian Gallucci wrote: > > > This is really weird -> > > > > ipfw: 1800 Deny UDP 216.174.91.28:138 216.174.91.31:138 in via xl0 > > ipfw: 1800 Deny UDP 216.174.91.28:138 216.174.91.31:138 in via xl0 > > ipfw: 1800 Deny UDP 216.174.91.28:138 216.174.91.31:138 in via xl0 > > ipfw: 1800 Deny UDP 216.174.91.28:138 216.174.91.31:138 in via xl0 > > ipfw: 1800 Deny UDP 216.174.91.28:137 216.174.91.31:137 in via xl0 > > ipfw: 1800 Deny UDP 216.174.91.28:137 216.174.91.31:137 in via xl0 > > ipfw: 1800 Deny UDP 216.174.91.28:137 216.174.91.31:137 in via xl0 > > ipfw: 1800 Deny UDP 216.174.91.28:137 216.174.91.31:137 in via xl0 > > ipfw: 1800 Deny UDP 216.174.91.28:138 216.174.91.31:138 in via xl0 > > > > We don't own any address space on 216.174.91.0 at all !! > > > > Can someone tell what this means ???
