and you could add that to /etc/rc.d/rc.local to run at bootup or
just add the route with the network GUI setup program.

Do you control the dsl router?  The simple way to handle extra routes
is to add them to the router that everything else uses as the
default. 

Alternatively, you could put 2 nics in the k12ltsp server and put
it between the dsl router and the rest of the network. However,
then you either have to change the subnet address on the DSL
router or everything else.  Then the k12ltsp server could do
dhcp and be the default gateway for everything else, and only
it would need the route to the mainframe.
