I’ve been using Zeroshell on a Routerboard 532a as my office LAN router for over a year now. It’s one of the best router operating systems that I’ve used and it’s really easy to set up. I’ve configured an OpenVPN connection to a remote office that I work with on a daily basis, and then set routing rules for the VPN’s internal IPs so that my office LAN can connect transparently to the remote LAN. Next, I’ve set up an OpenVPN server so that I and other users can log in remotely to my own office LAN. Routing and firewalling is set up between both VPN connections. Above that, we have the usual local routing, firewalling, DHCP and caching DNS server, inbound port mapping and so on.
Zeroshell runs on a regular Linux kernel, and SSH can be opened for full shell access. It doesn’t do anything that can’t be done manually via the Linux command line, but it’s an excellent and easy to use system that gets it done far quicker. It’s also proven to be completely stable, and allows me to max out the 65mbit DSL without issue.

Highly recommended and only takes as long to set up as writing the image to your CF card. Also compatible with Vmware.
