Jennifer,

Could be an Eggdrop script running on one of your servers that is causing 
this traffic.
Port 6667 is used for IRC (Internet Relay Chat).

Looks like it is on the box with the IP 69.50.163.130
Check the running processes on the box and look for anomalies.

Hi all,

I have been seeing a lot of strange traffic hitting my firewall and
cannot get a definite as to what it actually is.

access-group "outside_access_in"

From what I am seeing, it is from the same ip and src port - 6667 but
going to different ip and dest ports.  I have seen this activity from
numerous hosts and a dig cannot find anything about them.

I have seen an massive increase of this traffic over the last couple of
days and can't find any conclusive evidence that it may be a virus in
the wild.  Has anyone else seen this type of traffic?

Any information is greatly appreciated.
Jenn
