My laptop as a router/modem
Suppose my system (192.168.1.100) is in a LAN. In the LAN there are 2 other systems (192.168.1.101 as a system & 192.168.1.1 as a modem).
In my project, I need to route the packet between 192.168.1.101 & 192.168.1.1. Note that I can receive packets that there destinations are 192.168.1.101 or 192.168.1.1.
How to do?
Is there any registry value or sth like this to do?
Thanks a lot.
A LAN with three devices on those addresses would typically have a network mask that permitted 192.168.1.1 and 192.168.1.101 to talk to each other directly: no routing required. Unless you have an atypical network and your system is multi-homed, i.e. multiple network interfaces on different networks, then it will not be a router.
What exactly are you trying to do? Why does it have anything to do with Qt?
Hello dear ChrisW67.
Thanks for your response.
I have a project. In this project, I must be a Man In The Middle!
I can receive the packet that destined to 192.168.1.1 or 192.168.1.101.
In other words, I want to create an application like as cain & abel using Qt.
Hi, you use the same technique that Cain and Abel does on your LAN (or viruses for Xbox or PC do) it's called "ARP Spoofing":http://en.wikipedia.org/wiki/ARP_spoofing
Hi dear hskoglund.
Yes. I can receive packets from 192.168.1.1 that is destined to 192.168.1.101 & vice versa. But I dont know how to roue this packets that everything appears normal for 2 victim systems.
