So this route is installed on each machine in the external network. That
sounds fine.

You need to tell the edubuntu that it should forward packets between
networks (ie act as a router) or it will just ignore them. This is
generally done using
echo 1 > /proc/sys/net/ipv4/ip_forward
which you should try first.
However, you're asking it to route packets between two private network
ranges which linux may not be keen on (as it breaks some network rules).
One usually uses an iptables NAT rule in this instance but you may be able
to get away without it, I'm not certain off the top of my head.
