Scenario: There are three routers in use. Router A provided by ISP, routers B and C (both TP-Link Archer9) are used to segment computers on the network. Router B and C provides internet access for computers through router A.

10 computers has internet connections provided by router B, via router A. Two (2) computers serve as print and file server while the rest (8) as workstations that has file shares available to all in the workgroup Site1. (192.168.1.1-254)

12 computers has internet connections provided by router C, via router A. One (1) computer serve as print and file server while the rest (11) as workstations that has file shares available to all in the workgroup Site2. (156.27.30.1-254)

It is very important that the two sites are on different IP addresses and not see each other except as stated. Site1 is use for internal computing while Site2 is use for external computing.

However, two computers (server and workstation) from Site2 needs access to all computers on Site1 and its resources. While all computers on Site1 needs access to the two reference computers only on site2 and vice versa.

All computers has Microsoft Security Essentials and Windows Firewall at default settings.

Needs help how to set the network.
