I'm a big fan of pfSense - heavy home remote worker user, it stays up and connects to multiple OpenVPN servers, routing their spaces for my network, runs a remote access server inbound, an IPv6 tunnel via Tunnelbroker, multiple static IPs, including straightforward outbound NAT for my Apple TV to access NBA League Pass games (since the NBA in its wisdom has decided that the Puget Sound should be blacked out for Portland games and that I can just "tune into CSN Portland").
