Two diffrent Interet service on two workgroup in a network

  1. I live in India. I have 12 computers in two workgroup (9 and 3), also I have two different broadband plans of 2mbps on both workgroup.

    Now I want to join two networks which I can do with a switch (I think). the main issue is that if I joined the two workgroup in a single network how I can run internet on different workgroup separately. in other words I want different internet broadband lines to two workgroup and also want them in a single network.

    I run a shop have 9 computers as a cyber and 3 computers for working on a government website. and I don't want that cyber system use bandwidth of those three computers and also want these 3 computers to be on network so that I can monitor them from 1 place.

    Thanks....

    The key to your issue is where the 9 systems vs the 3 get DHCP replies.
    If the 3 systems go to one router, they will get a gateway address of that router AND each system will also get a DEFAULT route pointing to that gateway address.

    Here's my IPCONFIG, showing the gateway

    Ethernet adapter Local Area Connection:
    Connection-specific DNS Suffix . : socal.rr.com
    IPv4 Address. . . . . . . . . . . : 192.168.0.5
    Subnet Mask . . . . . . . . . . . : 255.255.255.0
    Default Gateway . . . . . . . . . : 192.168.0.1

    and the routing table that gets created with that connection; notice the line beginning with 0.0.0.0 - - that's the default.
    Code:
    IPv4 Route Table
    ===================================================================
    Active Routes:
    Network Destination		Netmask		  Gateway	  Interface  Metric
    		  0.0.0.0		  0.0.0.0	  192.168.0.1	  192.168.0.5	20
    		127.0.0.0		255.0.0.0		On-link		127.0.0.1	306
    		127.0.0.1  255.255.255.255		On-link		127.0.0.1	306
      127.255.255.255  255.255.255.255		On-link		127.0.0.1	306
    	  192.168.0.0	255.255.255.0		On-link	  192.168.0.5	276
    	  192.168.0.5  255.255.255.255		On-link	  192.168.0.5	276
    	192.168.0.255  255.255.255.255		On-link	  192.168.0.5	276
    		224.0.0.0		240.0.0.0		On-link		127.0.0.1	306
    		224.0.0.0		240.0.0.0		On-link	  192.168.0.5	276
      255.255.255.255  255.255.255.255		On-link		127.0.0.1	306
      255.255.255.255  255.255.255.255		On-link	  192.168.0.5	276
    You must make sure that the two routers have different addresses!!!

    Then the 9 systems will have their own gateway and route tables.

    Assuming the three systems have a router address of 192.168.3.1 and the 9 systems use 192.168.9.1 [the third digit is the number of systems just to make this discussion clear]

    then your problem becomes to connect the two networks inside the routing tables of all systems.

    MANUALLY, you add a route using
    on the 9.system side
    route ADD 192.168.3.0 MASK 255.255.255.0 192.168.9.x METRIC 1​
    on the 3.system side
    route ADD 192.168.9.0 MASK 255.255.255.0 192.168.3.y METRIC 1​

    That makes TCP see both sides but only resources specifically requested cross from one side to the other - - USING IP ADDRESSES. If you need print/file shares using names, you will need
    to add them to the drivers\etc\hosts file everywhere and the shared systems need fixed addresses :sigh:

    I am reluctant to lead you down this path UNLESS you are very experienced as this is considerable customization and will need to be well documented.
