Hallo Barry,

thank you for the reply.

All machines involved are Linux, a little walk in the building at least 
solved the gateway problem, now all machines see the bridged network as 
gateway, 172.***.***.***.
As a consequence now none of the laptops or pc's can access the outside 
world, they can only ping the internel NIC, aka the bridged network 
interface.
The Thinclients boot fine and they work ok, but yesterday I crashed the 
whole network when wanting to assign fixed ip adresses to printers and 
restarting dhcpd.....

Probably there is an error in ip setup I posted before, or in 
dhcpd.conf, but I did not change that:

default-lease-time            21600;
max-lease-time                21600;
ddns-update-style none;
allow booting;
allow bootp;
authoritative;

#host printer-canon {
#  hardware ethernet 00:00:85:57:a9:18;
#  fixed-address 192.168.66.235;
#}

option subnet-mask            255.255.255.0;

option domain-name-servers    172.31.100.254;

option option-221 code 221 = text;

shared-network WORKSTATIONS {
   subnet 172.31.100.0 netmask 255.255.255.0 {
      range dynamic-bootp 172.31.100.100 172.31.100.253;
      use-host-decl-names       on;
      option log-servers        172.31.100.254;

greetings, J.
