So, what I was wrong in my settings ?!?!
At VPN users I made the mistake to enter the IPs of my clients.
Removing these settings worked like a charm.
The only problem is that VPN doesnt allow broadcast to traver back and
forth in order to allow myself as a neighbour in the workgroup. Anyway
its ok, I think my problem is solved.
Tanks for everybody having the time and the patience to read my lines.
