I have noticed something very odd on my DNS server and was hoping someone could thell me what this means.. ipfw: 6300 Deny TCP 168.160.224.88:0 24.MY.IP.xxx:143 in via fxp0 ipfw: 65534 Deny ICMP:4.0 192.168.15.2 192.168.0.42 in via fxp0 My box has two nics with NATD running.. fxp0 = 24.MY.IP.xxx 255.255.255.0 fxp1 = 192.168.0.1 255.255.255.0 How did 192.168.15.2 get in ? This is private address space and my ISP does not have a route for anything on 192.168.0.0/16 so I'm try to figure out how they got to me and how they got in ? Next is there some kind of hole that has surfaced on port 143 ? I keep getting alot of connections on port 143.. I have the port blocked just wondering..
