[sudo-sys] Gateway dead, Private network down

The gateway has been replaced with a desktop computer sitting on its side in the rack on top of the multi-hd storage server. Note that this is super janky since the two PCI network cards can't be mounted properly in the somewhat-smaller-than-standard case. We added two network cards and were planning to use the built-in card as well, but currently the built-in card is not used and the private network is down. There are two reasons: * The switch used for the private network had one of its fans die and I turned it off until we can replace the fan so it won't overheat * The built-in network card appears to need firmware which I'm not going to bother with until the fan on the private network switch is replaced Also, we might get a new server rather than using this old desktop machine. The new computer is using the old harddrive. I changed the following files due to the different names of the network interfaces: /etc/network/interfaces /etc/default/isc-dhcp-server /etc/iptables/rules.v4 /etc/iptables/rules.v6 You can find backups of the files from before my changes at the same paths with .old added (for the parent dir for /etc/iptables) -- marc/juul
