Internets
Does your internet provider ever let you down? you get to the office only to find that today its not working. Well not any more, an upgrade to our router lets us make use of two ISPs simulataniously and when one lets us down, the other takes over.
This has been achieved with a nice and simple linux distro called 'Zeroshell'. As the name suggests there was no need to touch the shell as would have been the case trying to do this yourself and everything was quickly and simply setup.
In our setup we use the usb disk image as the main hard disk in a virtual machine. 3 bridges on the host machine allow it to connect to two ISPs and the internal LAN. Its a small distro with minimal memory usage (around 100mb) so is not costly to run on the vm host.
This has now replaced our physical routers, which now just act as wireless acess points, and we are able to have two separate wireless networks, one for 'n' devices and one for older slower devices. Our internal dns and dhcp was simple to setup, although i did have to remember how to use bind again as we had moved to using unbound in the old setup. Unbound is a really simple dns server which makes it really easy to override dns responses with internal addresses for services within our network, this avoids having to completly replicate the normal domain as you have to with bind.
We now also have OpenVPN server, we just need to think of a use for it :)
Overall zeroshell was quick and easy to setup, with no install process. lots of powerful features are assessible without every having to ssh and change config files manually.
