We had the same issue over here.
What we would have to do is ifdown eth1, boot the terminal and then ifup
eth1 and it would work, or just unplug the cable from eth1 and replug after
it boots, but that got old so we fixed it instead.
We had the 2 network cards plugged into two different switches, but we had
the switches connected together because we wanted to feed the ltsp terminals
to our network here in the library so we could pop a boot disk in any
computer and boot a terminal
The thing that fixed it was that we added a "route" command to send
broadcast requests to eth0 which is the terminal (internal) side of the
server. I think what was happening is that the server didn't know what to
do with the broadcasted request and was sending it to it's gateway of last
resort which was our main router here at the library and would never fill
the request to the client.
here is part of the new route output
Destination Gateway Genmask Flags Metric Ref Use
255.255.255.255 * 255.255.255.255 UH 0 0 0
Iface
eth0
(sorry if the formating of that output is messed up)
Here is the command that added it to our route. (It's been a while since we
did this so i think this is the command we used.)
route add -host 255.255.255.255 netmask 255.255.255.255 dev eth0
Also we denied all broadcasts on eth1 using /etc/sysconfig/ipchains config
file
#Thwack all broadcasts to eth1
-A input -i eth1 -p udp -d 0/0 137:138 -l -j DENY
-A input -i eth1 -b -s 0.0.0.255/0.0.0.255 -l -j DENY
This seemed to make the K12ltsp bridge very nicely into our network and we
are now able to go up to any computer in the building with a etherboot disk
and boot to a linux terminal
If you don't mind, could you let me know if this worked for you. I'm
curious to see if this was just some crazy coincidence or if these settings
really work as well as they do here.

I have a funny little thing that i do not understand.
I am using the k12ltsp and are new to Linux
I have to netcard in the server. One for the Thin client and one to access
the Internet trough a seperate local network.
Everything was workng well. Clients boots and all can access internet.
Then today the client cound not boot. It stoped when : Mounting root
filesystem /opt/ltsp/i386 from : 192.168.0.254.
Then i restart the server, with no netcable in the netcard giving access to
the Interenet. Then the client can boot but no internet. Then i tryed again
to restart and put the netcable to the internet on again and then the
workstations stops at the same place again. IT was working fine for 2days,
then this happend. There is also a DHCP server that provide IP address for
the "internet" netcard but as i have understood the system, it should not
give any problems, rigth?
Any idears what it can be
Thanks
