We have an ehternet LAN connected via Cisco router to Internet. Our ISP manage the Cisco router (we have no control on it).
I would like to know if it is possible to install a new router (NAT enabled) with two ethernet ports (one on Lan, one to the other router).
The main goal is to "hide" a part of the network behind the NAT router and also be independent from our ISP.
I someone has an idea ... ;-)
