Hi there,

In the past few days, my IDS has been picking up
traffic coming from port 20480 (on Internet servers)
to port 6667 (internal desktops). Both ports are
commonly used by trojan horse programs. Has anyone
else seens this? 

10/10-11:50:01.977897 204.x.x.x:20480 ->
192.168.0.199:6667
TCP TTL:255 TOS:0x10 ID:0 IpLen:20 DgmLen:195


Thanks,
Kip Sr.
