NetMan - pfSense

Download pfSense

Where to get it

Stuff it onto a thumbdrive

(really should create command-line instructions for this part)

If working from a Linux Mint machine GUI, right-click & extract the .gz file. Then right-click the resulting .img file & select "Make bootable USB stick".

If working from one of those crappy Windows machines, use Rufus...

If you're playing with a Mac... Yer on yer own for now.

Configure the Hardware

You'll want either a dual NIC or 2 (or more...) NICs.

A hard drive (or SSD) could come in rather handy...

Install pfSense

• Boot your machine from the thumbdrive. (UEFI is just fine...)
• Accept the copyright.
• Select "Install"
• Select "Continue with default keymap" (or, really, any keymap you like...)
• Select "Auto (UFS)
• Choose your disk for the install
  • I'd suggest only having one disk in the machine...
• Select "Entire Disk
  • Yes... Proceed.
• Select GPT (GUID Partition Table)
• Hit "Finish"
• Hit "Commit"
• Watch the pretty progress screens... (Or ignore it until it's done... Your choice...)
• When you see the "Manual Configuration" screen, Hit "No"
• Hit "Reboot"
• Go back & configure the machine to actually boot from the drive you installed pfSense onto...

Initial Configuration of pfSense

On first boot, pfSense will ask "Should VLANs be set up now [y|n]?"

Don't bother...

• Select your WAN interface
  • bce0 on this test machine (T310)
• Select your LAN interface
  • bce1 on this test machine (T310)
• Verify they're selected properly & say yes.
• Watch all the "done" messages scroll by (or not... again, your choice...)

After a moment or 3, you'll see the console menu.

Configuring pfSense from here...

At this point, you should be able to connect to the LAN port & point a web browser at 192.168.1.1

This is the Web-UI...

Default login is:

• Username: admin
• Password: pfsense

Change this. Do it NOW!

If you have the WAN port connected to the Internet, you should actually be capable of accessing the outside world right now.
