Today I received an information packet from Acacia Technologies Group 
informing me that I was in volation of their patent on "IAR" [1].  IAR is a 
US Patent 6,226,677 [2].  That packet suggest that I must license their 
technology or face legal action.  Has anyone else received this same 
extortion letter?

The claims the the patent text lead me to believe they don't have much to 
stand on.  If I read the abstract and claim one correctly then it doesn't 
cover a system that doesn't change the destination address.  Any solution 
that uses the IPFW fwd [3] rule would not modify the destination address and 
therefore does not meet claim 1.  I'm I correct in my logic?

What are your takes on this matter?
