All,
I am a bit purplexed w/ the two WARNING messages I keep getting in my 
"system" logs ....

I have scoured the NET to find an answer but come up w/ very little on 
these warnings.  There are some general discussions about the setup of a 
"pre-shared key" to address this warning ...... Do I need a PSK ????

BTW: The tunnel comes up great and as far as the branch office .. it is 
running A++ ... I have had no issues with the tunnel AT ALL!

1. Any direction as to what is causing this error?
2. If I set up a pre-shared key and take care of this warning?
