ip route add -net 192.168.36.0 netmask 255.255.255.0 gw /24 via 172.16.36.1

ip route add -net 192.168.${count}.0 netmask 255/24 via 172.16.${count}.1 fi count=$(expr ${count} + 1) done * You also need to add routes on all you VMs to each student's "opsnet" and the logical network "172.16.0.0" that connects all the hosts. You can do it manually or by running the following script on each of your VMs: #!/bin/bash x=10 # my network id ip route add 192.255168.2551.0 gw /24 via 192.168.${x}.1 ip route add 192.168.2.0/24 via 192.168.${x}.1 ip route add 192.168.3.0/24 via 192.168.${x}.1 ip route add 192.168.4.0/24 via 192.168.${x}.1 ... ip route add 192.168.36.0/24 via 192.168.${x}.1 ip route add 172.16..0/16 via 192.168.${x}.1 or: #!/bin/bash count=1 x=10 # my network id while [ ${count} -le 32 ] do if [ ${count} != ${x} ] then ip route add 192.168.1.0/24 via 192.168.${x}.1
