Thanks for the explanation.  Okay, I guess the other question I have is the 
LAST POLL ACK timestamp and sequence updates every 2 days but the LAST POLL 
REQ remains the same with no updated timestamp.  Doesn't a ACK require a 
new POLL REQ each time or does the LAST POLL REQ simply contain information 
on the time interval it needs to send ACK's back?  And does LAST POLL ACK 
only mean the box send a signal back without confirming whether the other 
end received it or not or is it basically telling you when the last time 
the other side confirmed the ACK packet?

Thanks,
John
