Sorry for the down time.  Our second router to die in two weeks died yesterday afternoon.  At first I thought it was something I did but then after restoring from a backup when it was working it still didn’t.  The vendor had changed the software in such a way that the translation of firewall rules from the user interface to iptables internally was no longer happening correctly resulting in a broken firewall that can’t be disabled.

Since I had no further spares to drop back to, I configured out of the Linux servers to act as a router until we can get one.
