You are right, it makes no sense to use IP dialing + internal routing. I was trying to write an example and I did stop to think it well. But you have manage to understand my question anyway. :)
The SendIP switch would be excellent for cases like this.
Thank you very much

Carlos,
when you are dialing by IP, using the internal policy doesn't make
sense, because its only looking at the dialed alias.
GnuGk can select different policy chains based on the type of alias and
the dialed prefix. But I find that already pretty complicated to debug
and if there is a better way to handle this I would prefer to not make
it any more complicated.
I think we might be missing a config switch which IPs a neighbor should
be queried about. Maybe a SendIP= switch similar to the SendPrefix=
switch.
Regards,
Jan
