Hmm, bizarrer and bizarrer.

Babel doesn't use prohibit routes -- its loop-avoidance mechanism uses
unreachable routes, which give (quite reasonably) EUNREACH:

  Network is unreachable

However, neither prohibit routes nor REJECT rules give the error
above, they give EACCESS:

  Permission denied

The message shown in the logs is EPERM:

  Operation not permitted  

Confused yet?
