Reverse Connect

Ok. Here's the deal.
I am running zbd at a client site and here at the office.
It works when I have the server here at the office and the customer connects
as the client.
Then they are running the add new client to connect.
 
What I want to do is have the customer be the zbd server. Use the reverse
connect to the zbd client listening here at the office. I would already have
the VNC server waiting and then just run a standard viewer to connect.
Can someone give me the command lines to run to accomplish this?
Here are the commands I use now thanks to William that work fine with the
zbd server in the office:
 
On my office machine:

start vncviewer -l

start zebedee -s -d -x "target localhost:5500/tcp"

On the customer PC, run the command line:

zebedee -d -e "{path to UltraVNC}\winvnc.exe -connect localhost::%d"

rhh.myvnc.com:5500

Thanks!
