Not a mIRC server, but IRC servers in general. There are other clients than
mIRC, such as PIRCH, vIRC, BitchX, etc.

I dont know much about port 20480, but 6667 is an attempt to connect to a
mIRC Server.

I dont know if 192.168.0.199 is a router IP or a pc, but if its a pc,
check to see if that pc has any IRC Server Software is installed.

(6667) is default port for a irc server.//

Just my 2 cents
Good Luck~

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.
