WAMP Test Server Home Network Security Firewall/Segregation?

[superfly611]

I'm setting up a WAMP server in order to see the progress on a project I am doing with a friend and miscellaneous developers. I would like to allow developers access to my WAMP server in order to track their progress and keep track of the progress of the project (Such as teamviewer which can record). I have one computer set up on Windows 7 with WAMP server running. My network consists of a Comcast cable modem that goes to my Asus RTN66U router and disperses to a bunch of computers and another D-Link switch for the extra connections to my network (just a bunch more computers on a network). I have wireless laptops and some hardwired computers but my Ultimate goal is to keep my NAS and network secure. What are my options/Best network security and how should I go about this? What settings should I set on my router (VPN or other and windows computer) in order to allow them access just to that one computer via team viewer or other means to work on the project website with the WAMP tester?

i also have a netgear fvs114 vpn/firewall I've had it for a while never really used it...

Any advice would be very welcome.

Thanks in advance
