[K12OSN] Lost MACs in routing ....

[norbert <bear2bar netscape net>]

Dear K12LTSP Sages....  :-)

I'm stumped and need help with a problem that .... well shouldn't be a 
problem....

Here's the specs!

First setup;

Cable Modem -> K12ltsp server -> hub -> thin clients & MACs (Both office 
& teaching)

this setup worked most of the time until the k12ltsp server was 
restarted ( just due to rewiring, not server problems) & then the MACs 
lost their connections until they were retarted .... but everything did 
work well

Second setup; (to allow for more growth and to separate the lab 
(thin-clients) from the office (MACs)

Cable Modem -> Router-> (a) K12ltsp server -> hub -> thin clients & MACs 
(teaching)
                                 -> (b) hub -> Office MACs
Here the Server, clients and the Office MACs work very well but the 
Teaching MACs cannot get out to the router ?????

The IP setup is as follows;

Cable Modem -> (DHCP)Router (192.168.2.1)-> (a) (Static eth1 
192.168.2.105)K12ltsp server & Gateway(static eth0 192.168.0.254) 
->(DHCP) hub ->(192.168.0.100 - 253) thin clients & MACs (teaching)
                                 -> (b) (DHCP 192.168.2.100 - 200)hub 
-> Office MACs

The thin clients & the server & the Office MACs all work well but the 
Teaching MACs cannot get "out" ??? They do get an IP address & can ping 
the server & the workstations but not the router!

Any & all help is greatly appreciated

thanks
