Pfsense is a fantastic piece of software which gives you fine grain control over pretty much anything and everything happening on ur network. One little thing which tends to be annoying at times is the default upload size for the captive portal in pfsense 1.2.3. Of course you dont want a text based login page, so here is how to change the upload limit of the captive portal:

  1. ssh into your pfsense box
  2. Use vi to edit the following file: /etc/inc/globals.inc
  3. Close to the top you will see the default captive portal size – add on two zero’s or tailor to ur needs.

Enjoy!
