Best way to connect to another LAN without the current LAN suffering security flaws
Posted on 2011-02-18
We have 2 LANs, one with segmentation of 198.168.55.xxx and the other LAN with 198.165.44.xxx.
The 198.168.55.xxx (referred as 55) has no Internet and is a small LAN with 5 computers wired together. The 198.165.44.xxx (referred as 44) is a larger LAN, a Domain, has Internet access and around 25 computers.
We want the small 55 LAN only to access a shared folder in the large 44 LAN; let's called SHARED folder.
We are thinking of adding a router in the 55 LAN and connect it to the 44 Large LAN. Then make the share of the single folder in one of the computers in the large 44 LAN.
When setting up the access to the large 44 LAN, we want to make sure that all PC within the small 55 LAN can't access the internet in the large 44 LAN or anything else in that large LAN.
To our understanding when we share a folder, only that folder is being accessed. However, we would like to advice of the EE group to recommend how to limit the access to the folder in the large 44 LAN. We don't want other PC from the small 55 LAN to hack that opening and jump out to Internet or other areas in the large LAN.
Our main concern is security.
