I have a computer with Windows 7 and two network cards:
NIC 1: 10.10.4.5/24 Gateway set to 10.10.4.1
NIC 2: 192.168.3.9/24 Gateway not set
When an application tries to make connection to a device (192.168.3.41) that is not connected (or ever has been) to the 192.168.3.0 network, a packet is sent to the gateway on the 10.10.4.0 network. This packet is refused by firewall rules and a TCP reset packet (RST, ACK) is sent back to the computer..
How can I sent up the computer to not send any packets bound for the 192.168.3.0 network to the gateway?
