Linux mapping nätverk ports
Dear expert
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?
Thx.

You should be able to set up a secondary IP address on that 1 NIC by editing your network interface:
...you can then map traffic and gateways according to your plan.
auto lo
iface lo inet loopback
auto eth0 eth0:0
iface eth0 inet static
address 10.1.1.2
network 10.1.1.0
netmask 255.255.255.0
broadcast 10.1.1.255
gateway 10.1.1.1
up route add default gw 10.1.1.1
down route del default gw 10.1.1.1
#Second IP same NIC
iface eth0:0 inet static
address 192.168.1.2
network 192.168.1.0
netmask 255.255.255.0

thx for answering
what happens if I want to add more interface to the laptop? like wireless APs and clients? I still need a hub/switch tho.

You should be able to add a wireless adapter if that's what you meant, you would need to add drivers for it.
You can add at least 2 virtual interfaces on that LAN port on your laptop, that are readily available to be use by your switch/hub.
And yes you will need a switch/hub for your clients.

thx for the answer again, is there any tutorial of how to do it, to map the network ports from hub/switch to debian console?
Depending on your level of Linux knowledge, this might be tricky:
Here is a link to set up OpenVPN on Debian Linux.
