Problem with kerio winroute firewall

[uniqueman2006]

hello

this is my first post

we are using kerio winroute firewall 6 to filter website access to client computers
i configured it as follows

there are 2 nic cards
1 is for internet and another is for lan
currently we are using airtel broadband with ip configuration
ip address for internet nic - 192.168.2.33
subnet - 255.255.255.0
gateway - 192.168.2.1


my lan ip address is (i.e.,domain ip) is - 192.168.1.100

we are sharing this connection to around 20 computers using nat

now i connect the dataone broadband connection i cann't browse the network, my whole network will go down

after connecting dataone i can browse internet only in server and not in any of the clients

dataone connection details are

ip address - 192.168.1.2
subnet - 255.255.255.0
gateway - 192.168.1.1

i am scratching my head since 15 days

pleeeeeeeeeeeeeeeese anyone help me in this issue

Your "WAN" and LAN networks are the same (192.168.1.0). Every other packet sent from the server computer goes to the wrong network since from the OS point of view both NICs are equal and it tries to balance the connections.

When the server wants to send a packet to the internet, it looks up the gateway (192.168.1.1). Then it looks at its network interfaces and sees that they are both connected to the 192.168.1.0 network. It picks randomly one of the interfaces and sends the packet away, not knowing that the gateway exists behind only one of the NICs. The same happens when you are trying to communicate with your local network.

Change one of the networks to some other address.
