At first we can install the new rules temporarily so that a reboot will reinstate the old rules. In the worst case the machine will go off the network so rebooting will have to be done from the local console. The script that installs the new rules saves the old ones in a restorable format so that in milder cases of malfunction the old rules can be reinstated from an interactive terminal session. Eventually we will make the new rules permanent so that they survive reboots. Note that you need superuser privileges to modify iptables rules.

Changes:
- Update ISOC.MocTicker.GenFilter, which generates a bash script that
installs the new rules. - Run the bash script on the machine whose rules we wish to change.
