There is a need to forward traffic between network cards. So the computer had two network cards:
1. Realtek PCIe GBE Family Controller IP address 192.168.1.2
2. HP NC112i 1-port Ethernet Server Adapter with IP address 192.168.0.1
The computer is used as a gateway server, and therefore two cards. Requires traffic on the first card (192.168.1.2) to transfer to the second card (192.168.0.1), and then to transfer to the computer of the subnet (192.168.0.83), and we are talking about a specific port number (12383). In other words, when the input of the first network card is traffic on this port, it eventually needs to be transferred to the second card, and then on the intra-192.168.0.83 computer on the same port. In this experience, so please help with commands in cmd, because they need to use route add and netsh interface portproxy add, but how exactly to write, I can not understand, I can't. In any case, Wireshark shows that traffic comes to the first network card and reset.
For a better understanding of the situation, here's a link to a screen with the current routing, maybe this will help - pixs.ru/showimage/Bezimyanni_8615114_28669182.png
