I have 2 desktops + 1 laptop and I'm trying to connect them without a router. The host desktop has 2 lan and 1 wlan interfaces:
1 Lan - Internet network (from the provider)
2 Lan - Local network with the second desktop
3 USB WLan - Local network with the laptop
The other desktop has only 1 lan interface and the laptop - a wlan interface.
My question is how can I have internet on all 3 PCs without a router?
