default bridge ifcfg-ltspbr0 address

I went back and changed the IP address information in
/etc/ltsp/dhcpd.conf and the clients are booting up to the login screen.
 When I enter the username and password, it waits for authentication and
then responds "The server is not responding, restarting".  I then have
the cursor and a blank screen...  The three files that have been edited
from the default setup are as follows:

ifcfg-eth0    added the BRIDGE=ifcfg-ltspbr0 line

ifcfg-ltspbr0  added the GATEWAY= to the end of file (our
subnet is and changed ip address from to

dhcpd.conf  changed to (address of
ifcfg-ltspbr0) and 172.31.100.X to 192.168.5.X throughout file

Any ideas why the authentication step would break?  I still have IP
tables running without any changes to the default setup.

Did you check your iptables rules? Disable it entirely for a quick test.
