  You probably haven't had it for long.  If it's been looping packets
for a long time, you would have noticed.

  Take a step back.  You have described a solution, not a problem.  Your
solution doesn't work, and therefore also doesn't solve the problem.

  So... what is the problem you are trying to solve?  Describe that.
Odds are that there is a solution that is *different* from what you
described above.  And, that solution will likely not have the endless
looping problem.

  Don't configure it so that it loops.
