I have a similar problem.
At first I thought it was an outside attack. Then the modem which was vry 
old and susceptable. Now it seems that I get horrible results even pinging 
myself.

My server is 63.199.8.158 and my router is 63.199.8.153
At the moment I have this running...
while true
do
  pyng=`ping -c 1 63.199.8.153|grep ttl|cut -d= -f4|cut -d. -f1`
   if [ `echo $pyng |cut -d" " -f1` -gt 1000 ]
   then
      netstat | grep :
      echo -e "\a " $pyng " \a"
   fi
  sleep 5
done

My pings from me to my own router can shoot from 10.5 to over 3000. So far 
one of the common factors seems to be that when it happens various postfix 
routines are running, and there are users checking mail on the imap 
connections. Im looking into trimming down postfix, and maybe dropping 
imap (which I only had running to support web-based email handling)

Not sure if that helps.
