Captive portal on multiple subnets



  • I download the pfsense 's book : Pfsense the definitive Guide but I don't get the figure 19.1 Captive Portal on multiple subnets . So I' d like someone to share this . Please !
    I recently read Pfsense multiple subnets in one  interface . Now I'd like to set captive portal On ALL THE SUBNETS .
    I also need to set the subnets to use external DHCP+DNS+LDAP

    Are you a commercial support subscriber or a customer of applianceshop.eu?

    If not, how did you get the book? If you contact the source of the file, and they get the request back to us, we can get a fixed version of the PDF.

    If you downloaded a pirated copy of the book, then don't expect any help. :-)

    If you actually purchased a real copy of the book, we might be more inclined to help. But if all you did was download a .rar of the book instead of paying for it, and you didn't buy the book or obtain it from an authorized distributor (like applianceshop.eu), then don't expect any help. The book is is not available for free from the Internet.

    As one of the authors of the book, I don't appreciate it being spread around like that. If you mention downloading it again, you will likely end up banned from the forum.



  • Sorry Jim !



  • Hello Jim,

    Is it possible for you to provide a copy of the updated handbook pdf to Jos Schellevis at the appliance shop?  He was able to provide me with the missing image but it seems he does not have an updated copy of the book…


    Hi Luis,

    It seems the xml book source does not include the picture, strange.

    However I have the full source including media, and the picture is part of that, so here it is:
    The picture is also attached to this email as png.

    Best regards,

    On another note... the following patch seems to do in software what your picture suggests should be done in hardware.
    If I create subnets using this approach

    and then apply this patch to /etc/inc/filters.inc

    I get subnets with Captive portal.  As far as I can tell these are very well behaved subnets. I can whitelist mac addresses and IP address on this subnet to bypass the CP as you would expect.

    Is there a reason we shouldn't implement this that you can see?

    I look forward to your response.

    That's all been reworked on 2.0, iirc it should work there out of the box now.

    I have a fix for the missing images in the book (And an e-mail from them asking for an updated copy) but I haven't had a chance to generate a new pdf with the fixes. I'll probably be getting that to them today.



  • Hello Jim,

    I look forward to the updated book. I will touch base with Jos in a few days to get the new version.

    We are running a customized version of pfSense 1.2.3 so it will be a while before we can upgrade to 2.0.  So we will need to settle for the above for now.  The only draw back I see is that src LAN_NET gets replaced with any in all rules.  I still have not been able to unscramble exactly why this allows the captive portal LAN subnets to work. There is some interaction between pf and ipfw that I am not quite getting… However, the bottom line is that for whatever reason changing that one line in filters.inc causes subnets to work with captive portal.

    Thanks for help and advise here and in other postings.

    take care.
