I work at a Non profit and another non profit is going in downstairs. they have asked to share our network so I purchased a wifi router, Trendnet TEW-731BR. Our Modem/Router uses the 10.10 address system and allows us to share printers and files.
They will be putting their own network printer and file sharing on the Trendnet TEW-731BR set with a 192.168.xxx.xxx network.
I tested and found that I could access a printer and other devices on the 10.10 network from the 192.168 network. I want to setup a firewall or other whatever that gives them internet connection only and limits their network to the 192.168 addresses.
I want to secure the 10.10 network by sending the 192.168 network straight to the Web. How do I do this?
P.S. I am thinking of this as a main network and a sub network. I want to send the sub network straight to the Web.
