I have linux box red hat 8.0 in 209.151.137.73, it acts a router.
it works for 209.151.137.74-78, the funny things, there is not any
problem to access 78, but 74 is not accessable.

 the following is the trace report. I called the company for
janefinch-core.ica.net , he said that is good for his router.
  so how can I verify if my linux box is ok?
