Loopback traffic on the net

Hi all,

after setting the snort rules for nimda to pass I enjoyed the sudden silence
screaming through my network.
But then I find this more philosophical entries in the logs:

Occuring from 4 ascending source ports: 62249 - 62252
All within in the same second.
First: 127.0.0.1 -> 62.208.xx.xx:80  ACK no payload
Then: 127.0.0.1 -> 62.208.xx.xx:80 RST payload 'tcp_lift_anchor, can't wait'

The destination is not within my jurisdiction but is on the same net as the sensor.

Don't know what that is or were it really came from. Only thing I know is that
it seems to be in a real hurry :)

CU Sven
