Hehe, I knew that question would get asked. The reason was because I
was out of town for a period when the BE server went down in a lengthy
power cut and didn't turn on when power was restored as it is
configured to do. So for a period of time I was away, the rest of the
family was stuck without internet access (which seems to have annoyed
them a lot). It is possible to configure dhcp3-server in a
primary/secondary configuration, but the modem obviously doesn't
support that through the user GUI. Now I have a raspberry Pi, I might
configure that as a backup secondary DHCP server and eliminate the
modem as a server.

So, it seems like it is possible that the IP changed after the backend
made a connection to it. Getting rid of the rogue DHCP server should
resolve the problem.

I agree. My server statically assigns IP addresses to all of my
'infrastructure'...so long as the modem doesn't interfere!

It is an ADSL modem that also does NAT and routing etc. (
http://homesupport.cisco.com/en-us/support/gateways/AM300 ) I am no
network guru, but I believe this gives me adequate security. Only a
couple of ports are exposed on the WAN side. Any other inbound
traffic should get dropped.
Confirmation of my networking assumptions would be greatly
appreciated, since I don't want to expose myself, my family, or my
