New pfSense User - Two Questions



  • OK, after some fiddling, I've got pfSense up and running on an older box.  I have two issues at the moment:
    (I've tried searches for both of these, nothing relevant to my issues came up)

    • pfSense handles subnet masks in a way I've never seen before.  I haven't always been a network guy, so that's not too surprising, but I need somebody to explain how 255.255.255.240 can translate into a two digit number?  Is there a special calculator I'm supposed to be using?  I'm on a static IP and I have to input the above subnet into pfSense before I can move on to anything else.  It would be great if somebody wrote a Wiki article on converting subnet masks for us uneducated people maybe?

    • On the actual pfSense box itself, the screen size is goofed up.  It's running on a 1200x768 17in widscreen format monitor.  It's displaying a 'fullscreen' size actual image, but it seems like something is screwed up somewhere.  At all of the prompts, the display is cutting off about 8 characters on the left and right sides of the screen.  I managed to get a HDD install done anyway by finding a few shots here on the forums of the command prompt, and I set the LAN IP to 192.168.1.2, so I'm into the web config on another box right now.  Is there any way to manually set the prompt resolution?  I don't know if this issue is terribly relevant, I've never used pfSense before so I don't know how often I'll want to access the actual command prompt on the box itself.

    2: Are you using firefox?

    IE is not supported:
    It is a firefox installer.

    EDIT: ah i think you're talking about the resolution on hardware ^^"
    I dont know about that.
    But you wont use it past the initial setup.
    You do everything via webGUI.

    You don't really need the console anymore. If you want to you can enable SSH or Serial port from WEB-GUI under system -> advanced and
    use putty to connect with. (Saving power to a monitor)

    pfSense uses a method called CIDR for subnet masking translations.  There are several different websites out there that perform online ip subnet calculations for you.  One of my favorites is at:  http://grox.net/utils/whatmask/

    Just enter in your ip address, full subnet afterwards, and you will receive the info you are looking for.

    Enjoy!

    Or just look at the wikipedia page i posted which contains a complete list of which /number is which netmask :)



  • Thanks very much for the help, I've got it up and running at this point.  I've got some more questions, but I'll post them under the sub forums where they should go.  Thanks again!
