I have never thought about such topology, so I belive this cannot be done. 
But what you are trying to accomplish is valid usage, so this can be 
classified as a bug. I'm currently very busy, but is a few days (probably 
in the beginning of the next week) I'll take a look at that. I belive 
fixing this should be relatively easy. What operating system are you using 
on the server and relay? As soon as I fix this, I'll prepare an unofficial 
version for you, so you can confirm (or deny) my fix.

I would also make things easier for me if you send me your relay.conf 
and server.conf files.

Cool image. What software have you used to produce it?

Thanks for your bug report. I have added bug #112 to the Dibbler bug
