Need help in networking in friend’s office.

There are two rooms with different MTNL Triband internet lines with respective routers.
Each router has 3 PCs connected to it for internet and file sharing.
Now we want all PCs in Room1 and Room2 to be in a network for file sharing but Room1 PCs should be able to access internet only from MTNL Triband 1 and Room2 PCs should be able to access internet only from MTNL Triband 2.

Please see the attached image to get an idea. network.jpg

Few questions:
Is the file server one of those 6 PC's?
DHCP is running on both the routers or are the PC's assigned static IPs?


Here's a possible solution:

-Enable DHCP on both routers. Room1 should assign 192.169.10.X, Room2 should assign 192.168.20.X (or any IP addresses as long as they are from seperate subnets)
-192.168.10.1 will be Router1 and it will be the default gateway for all PC's in Room1. 192.168.20.1 will be Router2 and it will be the default gateway for all PC's in Room2
-If one of the 6 PC's is the file server, lets say PC1 (IP say 192.168.10.10), then you will have to set up the routing on Router2 so that it knows about PC1. Just add a static route in which 192.168.10.10 is reachable via the interface on which the Cat6 connection is present (the inter-room connection).
-If the file server is not from one of the 6 PC's above, then you would have to decide in which room (and thus which subnet) will you be adding it to and then set up routing on that rooms router accordingly

The whole principle of working is that PC's in Room1 only know about Router1. So for internet, they will send all traffic to Router1 which will send it out through MTNL Triband Connection#1. Same for Room2 and MTNL Triband Connection#2
