Astaro Security Linux

If you are looking for an all in one security solution than you don't want to have your PC hooked directly into any form of modem. I use Astaro Security Linux as my firewall/router. I moved from a Linksys Cable/DSL router to this solution as I was noticing more and more security holes in linksys routing tables and capabilities. Basically you need an old PC a P3 500 will work great and 3 NIC's 2 min. 1 Nic (External Traffic) 1 Nic (Internal Traffic) 1 Nic (DMZ 'Optional') This software is free to home users and has very few limitations over a corporate version. You are able to set your own packet filterings, hosts, VPN, port forwarding (NAT) etc... also there is e-mail virus scanning if you have an e-mail server. It is very secure and flexible. As far as being able to connect to 2 different computers that share an IP address. You can use 2 different programs (VNC / PCAnywhere) that use different ports to communicate on and port forward accordingly.
