I wonder if this is possible to do and if its possible I need to know the tutorial of it, thx.
Im currently setting up and Debian linux system and planning using it as a firewall/VPN server. I only have one problem, the computer is a old laptop and it only got one network card.
Here is what I thought, to plug the laptop with a hub/switch and use those hub/switch to plug into internet/lan cable and mapping those ports from switch to firewall/VPN settings, is it possible to do? So for exemple: Hub/switch port2 is outside, port3-4 is inside. and also apply the rules to those?
