Hello Julian,
- have you tried getting rid on both sides of the
authentication over RIP?
- have you tried using a different key-string on both
sides, just as a test?
Sometimes one leave a space at the end of the password
and that will also be counted as a character ...
Hope any of this clues can help you ...
