I believe that your described network architecture causes the problems. 
(two times tjener with same ip). IMO a test network should be separated 
from your existing network using a gateway, one nic with IP 
attached to a switch connected to the new tjener main network, the other 
one attached to a thin client net of the old tjener with a fixed IP like (configured in old tjener's LDAP with GOsa²) and nat enabled 
on this gateway. Test clients could be attached to the new tjener's main 
network, if you lack network components.

To test the new network only in itself, just attach the new jener (nic 
with IP and a client to a separate switch.
