Netbook Pfsense machine
For a while I wanted to be able to know what traffic was coming and going from my network. Also I wanted it to be low power usage and not take up a huge amount of space. For a while I was piecing together the list of parts needed and would usually be about $400 or so to do this.
Now some people may be thinking just reuse an old small form factor pc like some of the Dell Optiplex or HP little pc’s. The only reason I did not go this route is the power they use and that I would have to buy one. Since I had this netbook (MSI Wind U100) here I only had to find my usb ethernet adapter.
Usb Ethernet adapter!!!!?????
Ok I know there are some peoples heads that just exploded! Yes I have made one of the ports needed to use the firewall a Usb ethernet adapter. The only bottle neck for me is the speed of my internet connection. I have 30mbs down and 5mbps up and the ethernet adapter works great!! I have had no issues that were fault of the netbook and ethernet adapter so far. It is running smooth. I am still in the beginning of the running and testing the system still, but having the peace of mind that I have blocked access from some countries so that their packets stop at my firewall and go no further is great!!
Plug the ethernet from the modem to the built in ethernet on the netbook.
Plug the ethernet adapter into a Usb plug and then plug an ethernet cable from that to your network switch or your wireless router WAN port.
!! Little warning!!
I was using the built in switch on my router to try and run my network, Pfsense was handling all DHCP but for some reason the router was causing issues. I at the moment have it setup with a 5 port switch feeding the network and router. All is working pretty well!!
If you have an old laptop or netbook that is pretty much useless to you now, why not give this a try!
I used this Ethernet adapter and if you grab it I can say with some certainty this is going to work as it is working for my application! https://www.amazon.com/gp/product/B00484IEJS/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
