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 broadcast-address 172.31.100.255;

option domain-name-servers 172.31.100.254;

option domain-name "ltsp";
option option-128 code 128 = string;
option option-129 code 129 = text;
option option-221 code 221 = text;
shared-network WORKSTATIONS {

greetings, J.
